Two concepts: PUBLISH vs LIST — never confuse them

This skill handles two fundamentally different concepts. Mixing them up is the #1 source of wrong answers.

Concept	What it means	Functions
PUBLISH (发布)	Make something accessible — a URL works, or code is on GitHub	publish_preview, unpublish_preview, list_published_previews, open_source, remove_open_source, list_open_source, get_open_source, fork, validate_open_source
LIST (上架)	Make something discoverable/purchasable on the marketplace	Free: list_in_dashboard, unlist_from_dashboard, delete_listing, get_listing_status<br>Paid: create_paid_service, submit_for_review, get_review_status, publish_service, unpublish_service, list_my_services, get_service, update_service, delete_service, restore_service<br>Browse + consumer: explore_marketplace, explore_services, get_service_detail, get_service_pricing, get_service_reviews, write_service_review, favorite_service, unfavorite_service, get_favorite_services, get_user_services, get_service_earnings, get_earnings_summary

Publishing does NOT auto-list. publish_preview() only allocates the URL. open_source() only pushes code. Neither makes the project discoverable on the marketplace — that requires a separate, deliberate LIST call.

Listing has two flows

Flow	When to use	Review?	Pricing?	Functions
Free listing	Free project, show on /projects gallery	No	No	list_in_dashboard()
Paid listing	Charge for access via x402	Optional (5-check self-report)	Yes (USDC on Base)	create_paid_service() → submit_for_review() (recommended pre-listing self-check) → publish_service()

POST /api/services no longer accepts service_type: "free_project". Free listing is done by list_in_dashboard() (the project gallery flow). Paid listing uses create_paid_service() + review + publish (the service API flow).

---

Visibility model — read this before answering "can others see it?"

A project's "publicness" is three orthogonal switches, not one:

Switch	Off state	On state	Flipped by
URL access	Visiting the URL returns 404	URL works for anyone who has the link	publish_preview / unpublish_preview
Gallery discoverability	Not on /projects gallery	Appears in the gallery	list_in_dashboard / unlist_from_dashboard
Marketplace listing	Not on the Service Marketplace	Discoverable + purchasable	create_paid_service + publish_service / unpublish_service

A project can be in any combination. Never collapse these into "is it public yet".

Status questions are read-only operations. Whenever the user asks:

• "is it visible / public / discoverable yet?"
• "上架了吗 / 在 dashboard 上吗 / 别人能看到吗"
• "is the listing live?"

The authoritative answer comes ONLY from a fresh get_listing_status(slug) (free) or get_review_status(service_id) (paid) call. Do NOT infer from past actions.

---

Project types — three only

type	What it is	Eligible for publish_preview()?
task	Scheduled cron/interval job	No (no HTTP port)
service	Long-running HTTP service (dashboard, API, page)	Yes
script	One-shot script	No (no HTTP port)

---

Routing — match user intent to the right action

A. Status intents — user wants to know current state

Sample phrasing	Action
"is it visible / public / discoverable / live?"	get_listing_status(slug)
"上架了吗 / 在 dashboard 上吗 / 别人能不能看到"	get_listing_status(slug)
"what URLs do I have published?" / "我发布了哪些"	list_published_previews()
"what's open-sourced?" / "都有哪些开源代码"	list_open_source(...)
"我的服务" / "my services" / "我的付费服务"	list_my_services()
"审核状态" / "审核通过了吗" / "review status"	get_review_status(service_id)

B. Action intents — user wants to change state

Sample phrasing	Action	Notes
"publish" / "share" / "make public" / "公开" / "发布" (no qualifier)	publish_preview(preview_id)	Allocates the URL only. Listing is NOT auto-flipped.
"list on the dashboard" / "上架" / "show on community" / "make discoverable" / "发到广场"	list_in_dashboard(slug)	Free listing. Requires the preview to already exist.
"上架付费服务" / "make this a paid service" / "上架到服务市场（付费）"	create_paid_service(...) → submit_for_review() (recommended) → publish_service()	Paid listing. Needs x402 config first.
"publish AND list" / "发布并上架"	publish_preview() THEN list_in_dashboard()	Two separate calls in order.
"remove from dashboard" / "下架" / "unlist" / "hide from gallery"	unlist_from_dashboard(slug)	Free listing only. Soft-unlist (sets is_public=false, review_status='unlisted', preserves stats). Preview URL stays alive.
"下架付费服务" / "unpublish service"	unpublish_service(service_id)	Paid listing only.
"open source" / "open-source the code" / "开源代码"	open_source(project_dir)	Pushes code to GitHub. Does NOT list.
"unpublish the URL" / "take down the link" / "停止服务"	unpublish_preview(slug)	Stops the preview container service only. Does NOT affect listing state (is_public/review_status unchanged). URL becomes inaccessible (404).
"remove the open source" / "delete from GitHub"	remove_open_source(slug)
"fork" / "install someone's project"	fork(source)
"提交审核" / "submit for review"	submit_for_review(service_id)	Paid only. Advisory self-check — never required for publishing
"发布服务" / "publish my service"	publish_service(service_id)	Paid only, works from any pre-listed state
"更新服务" / "update service"	update_service(service_id, ...)	Paid only
"删除服务" / "delete service"	delete_service(service_id)	Paid only
"删除项目" / "delete listing" / "permanently remove from marketplace"	delete_listing(slug)	Free listing only. Permanently deletes the listing row AND the community_slugs record. URL becomes inaccessible (404). Removes from both explore and my-projects. Use unlist_from_dashboard() to hide without deleting.
Ambiguous after rereading	Ask one question	"你是要 (a) 发布公开 URL，(b) 免费上架到广场，(c) 付费上架到服务市场，还是 (d) 开源代码？"

Cross-link via publisher: binding

When the same project has BOTH a public URL AND open-sourced code, you want them paired so the frontend renders "View Source" on the listing card and "Visit Live Demo" on the code card. This skill drives that pairing through one explicit binding in project.yaml.

How to declare the binding

Add a publisher: block to project.yaml:

name: my-app
type: service
version: 1.0.0
publisher:
  code_slug: my-app               # OPTIONAL — defaults to manifest.name
  public_slug: my-app-pub         # OPTIONAL — URL suffix; defaults to code_slug

Both fields are optional. If omitted, both default to manifest.name.

Either side can be published first

The gateway holds a pending entry until the second side arrives. No ordering requirement, no manual link step.

Order	What happens
open_source first → publish_preview second	open_source records pending entry; publish_preview consumes it and links
publish_preview first → open_source second	publish_preview records pending entry (needs publisher_code_slug arg); open_source consumes it and links

Manual repair (rare)

If a pairing was wired wrong (e.g. after a rename), use:

link_to_listing(listing_slug="2004-my-app-pub", code_slug="my-app")

PUBLISH: publish_preview() — public URL

publish_preview(preview_id, slug="", title="", publisher_code_slug="")

Map a running service to https://community.iamstarchild.com/{user_id}-{slug}.

• preview_id: from preview(action='serve'). Must be status=running.
• slug: URL suffix only (lowercase alphanumeric + hyphens, 3-50 chars). User_id prefix is added automatically.
• title: display name for the listing.
• publisher_code_slug: optional cross-link binding to a code project's slug.

Returns {"ok": True, "url": "...", "publisher": {...}, "hint": "...", "x402_detected": bool} — plus a next_step warning when x402_detected is true (complete the paid-listing chain).

Constraints:

• publish_preview does NOT create a paid listing. If the endpoint charges via x402 (returns 402), the publish flow is INCOMPLETE until you also run create_paid_service → submit_for_review (recommended) → publish_service — otherwise the marketplace shows nothing or "free". The return value flags this (x402_detected: true + next_step) when billing is detected.
• Max 20 published previews per user (gateway returns 429 over).
• Service must be running. Stops working when the container goes down.
• Only works inside the Starchild Fly container (needs FLY_MACHINE_ID).
• Listing visibility default is is_public=false. A successful publish_preview allocates the URL but does NOT make it discoverable. Discovery requires a separate list_in_dashboard() call.

Companions:

• unpublish_preview(slug) — stop the preview container service. URL becomes inaccessible (404). Does NOT affect listing state (is_public/review_status unchanged).
• list_published_previews() — all currently published preview URLs for this user.

---

PUBLISH: open_source() — push code to GitHub

open_source(project_dir, version_bump="patch", message="")

Push project source to community-projects/projects/{user_id}/{slug}/ on GitHub.

• project_dir: e.g. output/projects/my-task
• version_bump: patch | minor | major | none
• message: commit message body describing what this version changed. You (the agent) should always compose this based on the actual code changes you made in this session — never leave it blank if you know what changed. Aim for one to three short lines describing the user-visible change.

This is a PUBLISH action only — it does NOT list anything on the marketplace. To make a project discoverable, call list_in_dashboard() (free) or create_paid_service() (paid) separately after publishing.

Companions:

• fork(source, dest_dir=None) — install someone else's open-sourced project locally
• list_open_source(type=None, tag=None, user=None, q=None) — browse the GitHub catalog
• get_open_source(source) — fetch one project's full metadata
• remove_open_source(slug) — delete project directory from GitHub catalog (owner only)
• validate_open_source(project_dir) — pre-flight check before publishing

Project structure

Every project under output/projects/{slug}/:

project.yaml      # metadata (name, version, type, env_required, sc_proxy, publisher)
PROJECT.md        # required sections: What / Required env / How to start / Outputs / Troubleshooting
.env.example      # all env vars with placeholder values
.gitignore        # secrets blacklist
src/
  ├── run.py       # for type=task (must start: # -*- task-system: v3 -*-)
  ├── index.html   # for type=service (or app.py + frontend)
  └── main.py      # for type=script

---

LIST (FREE): list_in_dashboard() — show on /projects gallery

list_in_dashboard(slug, name=None, description="", cover_url=None, tags=None)

Make a published preview discoverable in the public gallery at https://community.iamstarchild.com/projects. Without this, the preview URL works but is invisible to anyone who doesn't already know it.

• slug: the full slug returned by publish_preview() (i.e. {user_id}-{suffix}).
• name: gallery card display name. Defaults to slug.
• description: ≤500 chars.
• cover_url: must be on storage.googleapis.com, image.thum.io, or api.microlink.io.
• tags: ≤5 tags, ≤20 chars each.

Returns {"ok": True, "listing": {...}, "url": "...", "dashboard_url": "..."}.

Constraints:

• Requires publish_preview() to have run first for the same slug — returns 404 otherwise.
• Idempotent: calling again with different name/tags updates the existing listing.
• No review, no pricing — this is the free listing flow.

Companions:

• unlist_from_dashboard(slug) — soft-unlist from gallery (sets is_public=false, review_status='unlisted', preserves view/favorite counts). URL stays alive. To re-list, call list_in_dashboard() again.
• delete_listing(slug) — permanently delete the listing row AND the community_slugs record (removes view/favorite counts). URL becomes inaccessible (404). Removes from both explore and my-projects. Use unlist_from_dashboard() to hide without deleting.
• get_listing_status(slug) — read-only check: returns {ok, exists, is_public, listing}.

LIST (PAID): Paid service listing on the Service Marketplace

Paid services charge for access via x402 (on-chain USDC settlement on Base). An automated 5-check self-report is available; the owner decides when to go live (review never blocks publishing).

Service lifecycle & review states (review is ADVISORY)

  create ──▶ published ──▶ submit_for_review ─▶ pending ─▶ approved / rejected
                │            (recommended BEFORE listing — advisory, never blocks)
                │                                    │ fix via update_service(), re-check
                ▼                                    ▼
           publish_service() ─────────────────▶ listed ◀─▶ unlisted (owner takedown / re-list)
                                                     │
                                                     ▼
                                          unavailable ──▶ restore ──▶ listed

Review is a self-check, not a gate: submit_for_review() runs 5 automated checks (api_reachable, pricing_consistency, x402_payment, response_match, doc_completeness) and stores a report for the owner. publish_service() works from any pre-listed state — the owner reads the report and decides when to go live. Recommended order: run the self-check BEFORE publish_service() so a broken endpoint is caught before buyers can pay for it. A rejected report does NOT block listing; a check run against an already-listed service never delists it.

⚡ Scenario Selection Decision Tree — MUST follow before creating any paid service

Step 1: Does the service have a Starchild project page (published via publish_preview())?

• YES, and the page is free to browse → Flow D. Use service_type="paid_project" + project_slug. The free page is published via publish_preview(), and the paid API sits behind x402 on /api/* routes. The upstream app serves the free intro page at / and the paid API at /api/*.
• YES, but the entire page requires payment → Flow B (Form 1). Use service_type="paid_project" + project_slug. The user implements their own access control (paywall + credential validation). See the x402 skill's "Paid Project: two forms" section.
• NO (standalone API, no project page) → Flow C or E. Use service_type="paid_api" WITHOUT project_slug. Do NOT create an index.html or publish a preview — there is no free page. The public URL root will show the x402 402 challenge or gateway info.

Step 2: Does the user want multiple API endpoints at different prices?

• YES → Use api_endpoints array in ONE create_paid_service() call (Flow E). Do NOT create multiple separate services.
• NO → Single endpoint, use api_endpoint only.

Step 3: Combine the answers:

User wants	Free page?	Multi-endpoint?	Flow	service_type	project_slug	api_endpoints
Paid subscription project (entire site behind paywall)	YES	NO	B	paid_project	required	—
Standalone paid API (no webpage)	NO	NO	C	paid_api	omit	—
Free intro page + paid API	YES	NO	D	paid_project	required	—
Free intro page + multiple paid APIs	YES	YES	D+E	paid_project	required	required
Multiple paid APIs (no webpage)	NO	YES	E	paid_api	omit	required

⚠️ Common Flow confusion mistakes (from real incidents)

Mistake	What goes wrong	Correct action
User says "write an intro page AND a paid API" but agent uses paid_api + creates a separate project preview	Service and project are disconnected — marketplace shows two items, one free (blank) and one paid	Use paid_project + project_slug (Flow D). The intro page and API are ONE service.
User says "pure paid API" but agent creates an index.html and publishes a preview	Unnecessary free project page clutters the marketplace; the intro page may show blank/JSON	Do NOT create index.html or publish_preview. Use paid_api (Flow C). The x402 gateway's 402 response IS the API's self-description.
User says "multiple API endpoints" but agent creates N separate services	N marketplace cards instead of 1; port conflicts; upstream confusion	Create ONE service with api_endpoints array (Flow E).
Agent reuses an upstream port already taken by another service	Gateway proxies to the WRONG upstream — responses are from a different service	Each service MUST have a unique upstream port. Check .x402/services.json for conflicts.
Agent creates start.py with /docs route that conflicts with upstream's /docs	Flask AssertionError: View function mapping is overwriting an existing endpoint	Do NOT define /, /docs, or /index.html routes in both start.py and the upstream app — define them in only one place.

Key rules:

• Do NOT pass project_slug for standalone paid APIs. project_slug belongs to paid_project only — including the "free webpage + paid API" pattern (Flow D, which uses paid_project). Passing a preview slug or a non-existent slug for a standalone paid_api creates a phantom association — the backend will silently clear it, but you should not have passed it in the first place.
• Routing rule: service tied to a project page → paid_project; paid_api is ONLY for standalone APIs with no project page. If your API has a published Starchild project (landing page/dashboard) that users can browse for free, use service_type="paid_project" + project_slug — this merges the service into the project card in the marketplace. If there is NO free project page, use paid_api and do NOT set project_slug. Passing paid_api + project_slug is auto-upgraded to paid_project by create_paid_service() (with a project_slug_warning in the response) — the final listing is always paid_project.
• project_slug must be the full published slug WITH user prefix (e.g. 33-my-app), and must correspond to an existing row in project_listings (i.e. publish_preview() + list_in_dashboard() must have been called first).
• api_endpoints is for services with multiple endpoints at different prices; each endpoint has its own path, price, and optional label.
• A project with project_slug set will NOT appear in the "Free" tab — it moves to "All" and "Paid" tabs.
• Merged-into-project-card visibility: when a listed service has project_slug pointing to a PUBLIC project, it is folded into that project's card in unified marketplace views. Consequence: the service will NOT appear as a standalone item in explore_services() or list_my_services() — this is by design, not a listing failure. It is still live and purchasable via the project card, get_service(service_id), and get_user_services(user_id), and it IS discoverable via explore_marketplace() (unified feed). To verify a merged service is listed, check get_service() → review_status == "listed", not explore_services() results.
• When the user asks for multiple APIs, create ONE service with api_endpoints — do NOT create multiple separate services. See Flow E.

Flow B — Paid Project listing

A paid project charges for access. There are two forms — both use service_type="paid_project" + project_slug:

Form 1: Entire page behind paywall — the page itself requires payment. The user implements their own access control (a login-like component with credential validation). The platform provides the x402 payment protocol; the user implements the paywall UI and credential logic. See the x402 skill's "Paid Project: two forms" section for implementation details and the "How to pay with Agent" documentation template.

Form 2: Free page + paid API — the page is free to browse, API calls cost money. This is Flow D (below). The upstream app serves the free intro page at / and the paid API at /api/*.

Both forms are the same pattern — the only difference is what the user implements (paywall interceptor for Form 1, nothing extra for Form 2).

1. Have a running project with a public URL (via publish_preview()).
2. Configure x402 charging on the project's access endpoint using the x402 skill. The endpoint must return 402 Payment Required when unpaid, and 200 + data after payment.
3. Create the service record:

create_paid_service(
    name="Premium Trading Signals",
    description="Real-time trading signals with on-chain confirmation.",
    category="数据服务",
    service_type="paid_project",
    project_slug="33-premium-signals",  # FULL published slug WITH user prefix (the URL path segment)
    api_endpoint="https://community.iamstarchild.com/33-premium-signals",
    provider_wallet="0xAbC...yourBaseWallet",
    pricing_model="monthly",
    price=10,
    service_description="Subscribers get a dashboard with live trading signals.",
)

Required paid-project fields: name, description, category, service_type, project_slug, api_endpoint, provider_wallet, pricing_model, price, service_description.

⚠️ project_slug must be the full published slug including the user prefix (e.g. 33-premium-signals, exactly the path segment in the project URL https://community.iamstarchild.com/<slug>/). The gateway derives the API endpoint as publicUrl + "/" + project_slug when api_endpoint is not set, so an unprefixed or wrong slug breaks endpoint derivation and the project↔service association. Fix an existing record with update_service(service_id, project_slug="<full-slug>") — no re-listing needed.

4. Recommended: run the self-check BEFORE listing — a broken endpoint listed on the marketplace can take buyers' money before you notice:

submit_for_review(service_id)   # kicks off 5 automated checks asynchronously
get_review_status(service_id)   # poll until no longer pending, then show the
                                # report to the user — THEY decide what to fix

A rejected report does not block listing. Read review_feedback + latest_task.checks, fix with update_service() if the owner wants, and re-run submit_for_review().

5. Publish once the report is clean (or the owner accepts the findings — review is advisory and never gates this step):

publish_service(service_id)

The check can also be run again later against a listed service — it never delists it.

Flow C — Paid API listing

A paid API is an external API service that already implements x402 charging.

⚠️ Do NOT pass project_slug for standalone paid APIs. project_slug is ONLY for paid_project (required) or the "free webpage + paid API" pattern (Flow D, where a published Starchild project page exists). For a standalone paid_api with no associated free project page, omit project_slug entirely. The backend validates project_slug against project_listings and silently clears non-existent slugs, but you should not pass it in the first place.

⚠️ Choose paid_project if the API belongs to a published Starchild project. If your API has a landing page / dashboard published via publish_preview() (i.e. it exists as a project on community.iamstarchild.com), use service_type="paid_project"

• project_slug=<full published slug WITH user prefix> (Flow B) — NOT paid_api. The project_slug is what links the service to the project card (pricing badge, cross-navigation). A paid_api listing has no project association, so the project card will keep showing "Free". Use paid_api only for truly external/standalone APIs with no Starchild project. Forgot the link? update the service record with project_slug — no need to re-list.

1. Have an x402-enabled API — the endpoint must return 402 when unpaid and 200 + data after a valid X-PAYMENT header. Use the x402 skill to implement this if needed.
2. Create the service record (service_type = "paid_api"):

create_paid_service(
    name="On-chain Whale Tracker API",
    description="REST API returning real-time whale wallet movements across 12 chains.",
    category="数据服务",
    service_type="paid_api",
    api_endpoint="https://api.example.com/v1/whales",
    provider_wallet="0xAbC...yourBaseWallet",
    pricing_model="pay_per_use",
    price=0.01,
    free_trial_count=3,
    api_documentation="# Whale Tracker API\n\n## GET /v1/whales\n\nReturns recent whale transactions.\n\n### Parameters\n| name | type | required | description |\n|---|---|---|---|\n| chain | string | no | Filter by chain id (default: all) |\n| limit | int | no | Max results (default: 50, max: 200) |\n\n### Response\n```json\n[{\"hash\":\"0x...\",\"from\":\"0x...\",\"to\":\"0x...\",\"value\":\"1000000\",\"token\":\"USDC\",\"chain\":\"base\",\"ts\":1700000000}]\n```",
    example_request="curl https://api.example.com/v1/whales?chain=base&limit=10",
    example_response='[{"hash":"0xabc...","from":"0x111...","to":"0x222...","value":"5000000","token":"USDC","chain":"base","ts":1700000000}]',
)

Required paid-API fields: name, description, category, service_type, api_endpoint, provider_wallet, pricing_model, price, api_documentation, example_request, example_response. Optional: free_trial_count (only for pay_per_use).

3. Publish → same as Flow B step 4.
4. Recommended self-check → same as Flow B step 5.

Flow D — Free Webpage + Paid API (hybrid)

Your project has a free landing page (published via publish_preview()) AND a paid API endpoint. Users can browse the project page for free, but API calls cost money. The marketplace shows a single merged card with both "Visit Project" and "Call API" buttons.

1. Publish the project via publish_preview() — this creates the free landing page.
2. Configure x402 charging on the API endpoint (e.g. /api/random returns 402).
3. Create the service record with service_type="paid_project" + project_slug:

create_paid_service(
    name="Random9 API",
    description="Random 9-digit number API. Free docs page + paid API calls.",
    category="工具服务",
    service_type="paid_project",
    project_slug="33-random9-api",  # FULL slug WITH user prefix — links to the free project page
    api_endpoint="https://community.iamstarchild.com/33-random9-api/api/random",
    provider_wallet="0xAbC...yourBaseWallet",
    pricing_model="pay_per_use",
    price=0.01,
    service_description="Paid access to the Random9 API endpoint; the docs page stays free.",  # required for paid_project
    api_documentation="# Random9 API\n## GET /api/random\nReturns a random 9-digit number.",
    example_request="curl https://community.iamstarchild.com/33-random9-api/api/random",
    example_response='{"random":"482917365","digits":9}',
)

The project_slug merges this service into the project card. The project page (/) stays free; only the API endpoint (/api/random) requires payment.

Note: if service_type="paid_api" is passed together with project_slug, create_paid_service() auto-upgrades it to paid_project and returns a project_slug_warning — the stored listing is always paid_project. Passing paid_project directly (as above) is the canonical form.

4. Publish + optional self-check — same as Flow B steps 4–5.

Flow E — Multi-Endpoint API

Your service has multiple API endpoints at different prices (e.g. basic $0.01, premium $0.10). Each endpoint is listed separately in the marketplace detail view.

⚠️ When the user asks for multiple APIs, create ONE service with api_endpoints — NOT multiple separate services. For example, if the user says "develop three paid APIs and list them", do NOT call create_paid_service() three times. Instead, create a single service with an api_endpoints array containing all three endpoints. This gives users a unified marketplace card where they can see and purchase individual endpoints. Only create multiple services if the APIs are truly unrelated (different domains, different audiences, different pricing models).

1. Configure x402 charging with per-route pricing:

   python3 skills/x402/scripts/monetize.py --name my-api --upstream-port 5173 \
     --mode pay_per_use --price 0.01 \
     --route "GET /api/basic=$0.01" --route "GET /api/premium=$0.10" \
     --route "POST /api/batch=$0.50" \
     --network eip155:8453 --facilitator $FAC
   

2. Create the service record with api_endpoints:

create_paid_service(
    name="Data API Service",
    description="Multiple API endpoints at different prices.",
    category="数据服务",
    service_type="paid_api",
    api_endpoint="https://example.com/api/basic",  # primary endpoint for review
    api_endpoints=[
        {"path": "GET /api/basic", "price": 0.01, "label": "Basic Query"},
        {"path": "GET /api/premium", "price": 0.10, "label": "Premium Query"},
        {"path": "POST /api/batch", "price": 0.50, "label": "Batch Process"},
    ],
    provider_wallet="0xAbC...yourBaseWallet",
    pricing_model="pay_per_use",
    price=0.01,  # price of the primary/default endpoint
    api_documentation="# Data API\n## GET /api/basic\nBasic data.\n## GET /api/premium\nPremium analytics.",
    example_request="curl https://example.com/api/basic",
    example_response='{"data":"basic market info"}',
)

You can combine Flow D + Flow E: use service_type="paid_project" + project_slug together with api_endpoints to link a free project page with multi-endpoint pricing. The marketplace shows a merged project card with an endpoint list in the detail view.

3. Publish + optional self-check — same as Flow B steps 4–5.

Self-check items (5 automated checks — advisory report, not a gate)

submit_for_review() runs these checks against the api_endpoint; the report is for the owner — failures never block or take down a listing:

#	Check	What it verifies
1	api_reachable	The endpoint returns 402 Payment Required when no X-PAYMENT header is sent
2	pricing_consistency	The amount in the 402 response's accepts matches the price you declared (in USDC base units)
3	x402_payment	After a valid x402 payment, the endpoint returns 200 + data
4	response_match	The actual response's key fields match your example_response
5	doc_completeness	api_documentation includes parameter descriptions, response format, and at least one example

Check #5 is keyword-matched: the doc must contain a "Response" (or "响应格式") section with actual body text under the heading — an empty section fails review. service_description (paid_project) and api_documentation / example_request / example_response (paid_api) are enforced at call time by create_paid_service(), which errors before creating an unreviewable record.

Common rejection causes:

• 402 response amount doesn't match declared price (off by decimals / wrong unit).
• Endpoint doesn't return 402 at all (x402 not wired up, or returns 200 to unauthenticated requests).
• example_response doesn't match what the API actually returns after payment.
• Documentation missing parameter table or response schema.

Pricing models

All paid services use the x402 exact payment scheme (on-chain USDC settlement on Base).

pricing_model	Meaning	x402 behavior	Typical use
pay_per_use	Per-call charge	Every request with valid X-PAYMENT → settle (charge)	API calls
lifetime	One-time buyout	First payment settles; subsequent requests verify past settlement, no re-charge	One-time purchases
monthly	Monthly subscription	Settles once per billing month; re-charge after expiry	Web subscriptions, API monthly plans
weekly	Weekly subscription	Settles once per 7 days; re-charge after expiry	Short-term subscriptions
quarterly	Quarterly subscription	Settles once per 90 days; re-charge after expiry	Quarterly plans
yearly	Yearly subscription	Settles once per 365 days; re-charge after expiry	Annual plans (often discounted)
prepaid	Prepaid balance	User deposits via deposit-settle (one on-chain tx), then each call debits balance off-chain (zero gas)	High-frequency micro-payments

free_trial_count is only valid for pay_per_use — allows N free calls before charging.

Multi-plan (multiple pricing options)

A service can offer multiple pricing plans simultaneously (e.g. weekly + monthly + yearly). Pass pricing_options array when creating the service:

create_paid_service(
    ...,
    pricing_options=[
        {"pricing_model": "weekly", "price": 3, "is_default": True, "label": "Weekly"},
        {"pricing_model": "monthly", "price": 10, "label": "Monthly"},
        {"pricing_model": "yearly", "price": 90, "label": "Yearly (Save 42%)"},
    ],
)

Rules:

• pay_per_use cannot be combined with other pricing models.
• Subscription models (weekly/monthly/quarterly/yearly) can be freely combined.
• lifetime and prepaid can be combined with subscription models.
• One option must be marked is_default: True (or the first is auto-marked).
• The service's pricing_model and price fields are auto-synced to the default option.

Multi-plan 402 requirement: The service's x402 middleware must support the X-Pricing-Model header — when a client sends X-Pricing-Model: yearly, the 402 response must return the yearly plan's price. Review verifies each plan's 402 amount individually.

Reference: See x402-facilitator/docs/pricing-models.md for the full specification.

Paid service management functions

Function	Purpose
create_paid_service(...)	Create a service record (published state)
submit_for_review(service_id)	Run the 5-check self-report (advisory)
get_review_status(service_id)	Poll review progress + per-check details
publish_service(service_id)	Go live (any pre-listed state)
unpublish_service(service_id)	Take down (listed → unlisted)

Project cards + standalone services in one feed (same as web All/Paid tabs); the only search path that surfaces services merged into public project cards. Items have type: service (use id) or project (paid cards carry service_id) — feed into get_service_detail()
explore_services(search, category, sort, ...)	Browse STANDALONE service items only (services API). ⚠️ Services merged into a public project card do NOT appear here — use explore_marketplace() for full coverage
get_service_categories()	List all categories with counts
get_service_detail(service_id)	Public detail for a published service (includes docs, increments views)
get_service_pricing(service_id)	Verified pricing with real-time x402 check
get_service_reviews(service_id, sort)	List reviews for a service (public)

Behavioral rules

• Show the diff before open_source(). After validate_open_source, summarize what's about to be pushed and ask for confirmation. Exception: explicit "publish without confirmation" or re-publish of a known good project.
• Never auto-run setup.sh on fork. Show the command, let the user confirm.
• Always collect env in one batch on fork. Read project's env_required, diff against workspace/.env, call request_env_input ONCE with the missing keys.
• Review is advisory. publish_service() works without review; still OFFER the self-check (submit_for_review()) so the owner sees whether buyers can actually pay before/after going live. Show the report to the user — the decision is theirs.
• api_endpoint must be the x402 charge endpoint. For paid projects this is the project's public URL. For paid APIs it's the external API URL. The reviewer hits this URL expecting a 402.
• Price unit is USDC. The 402 response's accepts.amount is in base units (6 decimals for USDC). A $0.01 price → amount: "10000". Mismatch here is the #1 review failure.
• Don't fabricate review results. Always call get_review_status() to check — never assume the review passed because you submitted it.
• Don't conflate publish and list. publish_preview() allocates a URL. list_in_dashboard() / create_paid_service() makes it discoverable. These are separate, deliberate steps.
• Slug rules: lowercase alphanumeric + hyphens, 3-50 chars, no leading/trailing hyphen.
• Version rules (open_source): strict semver. Re-publishing same version is rejected.
• URL ≠ code ≠ listing: a public URL going down does NOT remove the open-source code or the marketplace listing, and vice versa. They're independent.
• Do NOT pass project_slug for standalone paid_api services. project_slug belongs to paid_project only — including the "free webpage + paid API" pattern (Flow D, which uses paid_project; passing paid_api + project_slug gets auto-upgraded to paid_project with a project_slug_warning). Passing a preview slug or non-existent slug for a standalone API creates a phantom association. The backend silently clears non-existent slugs, but you should not pass project_slug unless the user explicitly wants to link a free project page with the paid API.
• When the user asks for multiple APIs, create ONE service with api_endpoints. Do NOT call create_paid_service() multiple times for related APIs. Use the api_endpoints array to list all endpoints in a single service (Flow E). Only create multiple services if the APIs are truly unrelated (different domains, different audiences, different pricing models).

Common gotchas

Symptom	Cause	Fix
publish_preview: Preview not found	Wrong preview_id, or service was stopped	Check /data/previews.json, restart with preview(action='serve')
publish_preview: 429 Too many published previews	Hit 20-per-user gateway cap	unpublish_preview() something old first
publish_preview: FLY_MACHINE_ID not set	Running locally, not in Starchild container	URL publish only works in the production container
list_in_dashboard: 404 No preview found	publish_preview() hasn't run for this slug yet	Call publish_preview() first
open_source: 400 Validation failed: env names not in .env.example	Listed MY_KEY in env_required but forgot .env.example	Add the missing key to .env.example
open_source: 400 Possible secret detected	Secret scanner found a real-looking API key	Move to env var; .env.example value should be your-key-here
Marketplace shows service as free / missing after publish	Only publish_preview() was run — URL publish ≠ paid listing	Complete the chain: create_paid_service → publish_service
create_paid_service: 400 Free services should be published through the Project publish flow	Tried service_type: "free_project"	Use list_in_dashboard() for free projects, not create_paid_service()
publish_service: 400 not in a publishable state	Service is already listed, unavailable, or deleted	Check get_service() state; unavailable → restore_service()
submit_for_review: 400 Free services do not require review	The service record was created as a FREE type — the paid payload was built by hand (missing service_type/wallet/pricing) instead of via create_paid_service()	Delete it and recreate with create_paid_service() (all paid fields are required positional args, so this cannot happen through the function)
Review rejected: pricing_consistency failed	402 response amount doesn't match declared price	Ensure amount = price * 1000000 (USDC 6 decimals)
Review rejected: api_reachable failed	Endpoint doesn't return 402	Wire up x402 charging on the endpoint first
create_paid_service response has project_slug_warning	Passed project_slug for a paid_api but the slug doesn't exist in project_listings	Backend cleared it automatically. If this is a standalone API, don't pass project_slug. If you intended Flow D, publish_preview() + list_in_dashboard() the project first, then update_service() with the correct slug.
create_paid_service: 500 Failed to create service after delete→create cycles with the SAME name	Deleted services keep their slug (soft delete), and slug generation only tries a limited number of suffixes — repeated delete/recreate with one name exhausts them	Do NOT wait and retry — the failure is permanent for that name. Use a different service name, or restore_service(service_id) + update_service() instead of delete+recreate
Created multiple services when user asked for "multiple APIs"	Called create_paid_service() once per API instead of using api_endpoints	Use Flow E: one create_paid_service() call with api_endpoints=[...] array. Only split into multiple services if the APIs are truly unrelated.
