# Apiosk Gateway

> Apiosk is the comparison layer for agentic commerce. Listings are grouped by the job they perform, so an agent that needs a task done gets every provider that can do it in one call, priced side by side, with an input mapping that makes the offers substitutable. Three chained endpoints do the comparing, and none of them charges anything: GET /v1/discover (what can perform this task, with stable candidate ids), GET /v1/compare (how those candidates perform against your requirements, scored 0-100 with the weights and per-dimension contributions that produced the number, so it can be recomputed rather than trusted) and GET /v1/decide (one provider back, the rule that picked it, every rejection with the constraint that caused it, and the runners-up in order). Browse the jobs with GET /v1/capabilities; get the candidates for one, cheapest first, with GET /v1/capabilities/{slug}. The call you pick is paid per request over x402 (HTTP 402 + USDC), with no accounts, API keys or SDKs. Describe a need in plain words at GET /v1/search and get the providers ranked. Price, settlement rail and input compatibility are compared for every offer; measured latency and success rate are published for the listings Apiosk has proxied enough calls of, and explicitly absent for the rest. Result quality is not measured anywhere.

## Skills
- **Discover, compare and decide between providers** — The part a provider's own API cannot answer: how it compares to the alternatives. Three chained endpoints, none of which charges anything. GET /v1/discover retu
- **Do a job end to end: decide, pay, return the answer** — POST /v1/do collapses the whole chain into one authenticated call: describe a job in plain words, and Apiosk parses it, finds the candidates, scores them, picks
- **Discover paid resources** — The x402 discovery document: payable resources with the spec-shaped accepts[] a live 402 carries. Publishes managed listings (hosted, priced and settled through
- **Discover APIs** — List every active, verified listing with its provider, pricing, endpoints, schemas, examples and pricing rules. Filter on search, category, tag, listing_type, m
- **Discover providers** — Browse who publishes on the gateway (name, username, avatar, bio, sector, listing count), most listings first, then open one provider's catalog.
- **Read API metadata** — MCP-style, agent-native manifest for one API: operations, input/output schemas, pricing, tool annotations.
- **Execute an API** — Call any listing through the uniform execute contract or the transparent proxy path — every listing is gateway-hosted. Paid endpoints return HTTP 402 with x402
