Available tools 3

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

apis

list_apis

Browse the live catalogue, optionally filtered to one category. Omit category for everything. Returns settlement-verified listings only unless verified_only is false. Free and read-only; spends nothing.

search_apis

Free-text search across the live catalogue. Matches listing name, description, category and provider name. Returns settlement-verified listings only unless verified_only is false. Free and read-only; spends nothing.

api

get_api

Fetch a single live listing by its id or slug, including base_url, price range, network and verification state. Also returns a reliability object: score (0 to 100 or null), band (strong, established, thin, caution or unscored) and computed_at. Reliability is a running score from paid verifications, health history and payTo integrity, not a star rating and not a guarantee; unscored means it has not been computed for that listing yet. Method: https://payapi.market/how-an-agent-finds-payapi. Returns the listing whether or not it is verified, and reports payment_verified honestly. Free and read-only; spends nothing.

PayAPI Market — questions

Answers built from our own checks of this server.

What can PayAPI Market do?

It exposes 3 tools, read directly from the server on our last check. Among them: get_api, list_apis, search_apis. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is PayAPI Market working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 337 ms. The bar chart above shows every period we have measured.

How do I connect PayAPI Market?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does PayAPI Market need an API key?

No. PayAPI Market completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is PayAPI Market?

It answers our handshake in 337 ms on average, which is faster than 52% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
