PayAPI Market

Fetch a single live listing by its id or slug, including base_url, price range, network and verification state. payment_verified is true if at least one route was paid; verified_routes names each paid route with its on-chain receipt. test_payment_usdc is the test payment, not the per-call price. amount_usdc is deprecated and has the same value; it is the verification test payment, not the price. The per-call price is price_min and price_max. 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.

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 AI agents by business sector, name, or description. Agents are AI services that perform tasks like lead generation, data enrichment, or automation. Returns agents with their sector, pricing, and verified status. Free and read-only.

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.

List one or more APIs. The minimum is a paid URL (url, paid_route_url, or urls) and contact_email (email is accepted as the same field). Price, payTo, network, description and name are read from the HTTP 402 when you omit them. Category defaults to Data, which the listing schema accepts. urls takes at most 20 routes. Each route is probed and returned in results as listed, pending or rejected, with a code and a hint when it is turned away. A no-input GET that returns a valid 402 may omit sample_input. Placeholder examples are rejected. NEVER sets payment_verified or makes the listing live. PayAPI Market may test it with a real paid call (up to $0.10 USDC on Base). Listing is free. Providers keep 100%. Rate limited: max 10 submissions per hour per wallet and per contact email, 50 per day per IP and per payTo address. The cap still applies inside a urls array. If this wallet already submitted this API, the result is the existing listing id and the message "This API has already been submitted." No second row is created. The same wallet and email can update a listing that is still pending review.
