Indexers sweep this fleet host by host, endpoint by endpoint — dozens of free trial calls to learn what is for sale, at what price, and whether it is up. This endpoint sells that sweep back as a product: one paid call, $0.005 USDC on Base, returns the canonical catalogue of the entire fleet.
| Field | Meaning |
|---|---|
endpoints[] | Every paid endpoint in the fleet catalogue: slug, name, method, url / call_url, live effective price_usd, one-line description. |
endpoints[].status | Current probe result from the fleet's own 5-minute prober feed: up, http_status, latency_ms, plus the feed timestamp. This is a current status, not a historical uptime percentage. |
endpoints[].example | A worked paid-call example per endpoint: method, URL, example request body where the endpoint declares one, and the exact payment requirements (amount in atomic USDC, asset, payTo, network). |
worked_example | One fully narrated 402 → sign → settle → verify example (for /brief) using live prices. |
The index is generated from live artefacts at request time — the fleet well-known manifest and the status prober feed — never from a hand-maintained copy, so prices and status cannot silently drift from what the endpoints actually charge and return.

Any x402 client works — @x402/fetch, the code generator can scaffold one, and the free wallet-health pre-check tells you whether your wallet can settle before you try.
GET /clinic/codegen lists slug / name / method / price / URL for free — no examples, no status, no per-endpoint payment requirements. GET /clinic/status-feed gives the current fleet status for free. The paid index is the bundle an indexer actually needs in a single call.
Price is this endpoint's own: $0.005 per call, settled in USDC on Base via x402 v2, no account, no subscription. If a settled call fails on our side, the response carries an r435 retry-insurance token that fetches the index free within 24h. Verify any settlement at the settlements page.
