api record

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…

_ used through this hub 30 days

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

inferred, not observed

Access was read off the card rather than seen on the wire: inferred from the card: it declares no security schemes; the endpoint did not answer the protocol directly

_ what it can do 7 tools
7 never probed 0 of 7 classified

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • discover-providers reads unknown never probed

    Browse who publishes on the gateway (name, username, avatar, bio, sector, listing count), most listings first, then open one provider's catalog.

  • execute-api moves money unknown never probed

    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 payment requirements until a payment proof is supplied.

  • do-job moves money unknown never probed

    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 one, fills the winner's own documented parameters in from your words, pays it from the wallet behind your connect token (created once in the buyer portal, carrying the spending caps you set there), and returns the provider's response with the payment receipt. Fail-closed: nothing is paid when no capability matches (404), when every candidate fails your constraints (409), or when the provider requires a parameter your job did not state (422) — the missing values are named instead of guessed. Send dry_run=true for everything except the payment. GET /v1/do documents itself.

  • read-api-metadata reads unknown never probed

    MCP-style, agent-native manifest for one API: operations, input/output schemas, pricing, tool annotations.

  • compare-providers reads unknown never probed

    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 returns the candidates that can perform a task, each with a stable candidate_id. GET /v1/compare turns those ids into evidence — price, measured latency, measured success rate and input compatibility side by side, each scored 0-100 alongside the weights and per-dimension contributions that produced the number, so it can be recomputed rather than trusted. GET /v1/decide returns one provider with the rule that picked it, every rejected candidate and the exact constraint that removed it, and the runners-up in order. State constraints once (max_price, max_latency_ms, min_reliability, settlement, require_all_inputs, optimize_for) and pass the same ones down the chain. Dimensions Apiosk has not measured are dropped from the weighting and named, never scored zero.

  • discover-paid-resources reads unknown never probed

    The x402 discovery document: payable resources with the spec-shaped accepts[] a live 402 carries. Publishes managed listings (hosted, priced and settled through Apiosk) by default; add ?include=federated or ?include=all for the external endpoints Apiosk indexes but does not proxy. Paginated — items[] is one page, and resources are served best-documented first, so the first page is the part you can call without a second round-trip. Walk links.next; narrow with ?category=, ?q=, ?contract=documented and ?perPage= (max 100). meta.categories lists every category with its counts and a ready-made URL.

  • discover-apis reads unknown never probed

    List every active, verified listing with its provider, pricing, endpoints, schemas, examples and pricing rules. Filter on search, category, tag, listing_type, min_price, max_price, created_after, created_before; sort by name, price or newest. Results are ranked managed-first: listings Apiosk publishes and operates come before federated listings it only executes, with the requested sort applied within each group (see meta.ranking). Every listing is called and settled through the gateway either way.

_ try it over a2a through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

card completeness
90%

How much of the published card is filled in. Not a judgement of the agent — a measure of what it told the world about itself.

spec deviations
0

Places where the published card departs from the specification. Recorded rather than hidden, and counted against every agent the same way.

Served from the same domain, which is what was measured. Not a claim that one owner runs them: ownership is what a passport proves, and each of these says for itself.
