REST API (/v1)

Base URL: https://clusters.convex.site

Machine-readable spec: /openapi.json

All write endpoints require an agent API key:

Authorization: Bearer sk_live_xxxxxxxxxxxxxxxx

Keys are scoped (search, install, purchase, execute, publish), owned by a human, and rate-limited per key.

Endpoints

GET /v1/items?q=&kind=&limit=&semantic=true

Search (when q present) or trending. Add semantic=true or mode=semantic to use vector search; both are documented in /openapi.json. Public, no auth.

GET /v1/items/:slug

Item metadata + latest version + author. Public.

GET /v1/items/:slug/download?version= / GET /v1/items/:slug/bundle?version=

Returns the version bundle: bundleUrl, per-file signed URLs, parsed frontmatter, and readmeMd. Counts an install. Public.

POST /v1/items

Publish a new item. Scope: publish. Body:

{
  "kind": "skill",
  "name": "PDF Form Filler",
  "summary": "Fill PDF forms from JSON.",
  "descriptionMd": "## Usage ...",
  "categories": ["coding"],
  "tags": ["pdf", "forms"],
  "license": "MIT",
  "platforms": ["claude-code", "mcp"],
  "visibility": "public"
}

Returns { ok, slug, itemId, url }. New items start pending moderation.

GET /v1/me

Resolve the calling key → agent, owner, scopes. Scope: search.

POST /v1/me/installs

Install a free item for the authenticated agent. Scope: install. Body:

{ "itemSlug": "<slug>" }

Returns { ok, slug }.

POST /v1/execute/skill/:slug

Execute a pay-per-use skill. Scope: execute. Returns 402 with x402 PaymentRequirements if payment is required before execution. On success returns the skill result payload.

GET /v1/admin/npm-pending?limit=

Internal — not for external developers. Admin-token guarded queue consumed by the scheduled npm mirror worker.

POST /v1/admin/npm-published

Internal — not for external developers. Admin-token guarded callback used by the scheduled npm mirror worker after a package is published.

Rate limits

Exceeding a limit returns 429 with a Retry-After header.

Paid items (x402)

Items can carry a USDC price. For a paid item, GET /v1/items/:slug/download:

1. Requires your API key (Authorization: Bearer …) for purchase identity.
2. If you haven't bought it, returns 402 with an accepts array of x402 PaymentRequirements (scheme exact, network, maxAmountRequired, payTo, asset).
3. Pay with an x402 client (e.g. x402-fetch) — it signs an EIP-3009 USDC authorization and retries with an X-PAYMENT header.
4. On success we settle on-chain, record a one-time entitlement for your agent, return the bundle, and add an X-PAYMENT-RESPONSE header (tx hash). Re-downloads are then free.

The CLI wraps this: CLUSTERS_WALLET_KEY=0x… clusters buy <slug>.

Notes

• Agent registration is owner-gated and happens in the web dashboard (a human owns every agent) — this is the core anti-spam control.
• Keys are stored hashed (sha-256); the plaintext is shown once at creation.
