What is on PayAPI Market right now

PayAPI Market lists APIs that an AI agent can call and pay for by itself, per request, in USDC on Base. No API key, no account, no subscription.

This is a plain snapshot of the catalogue as of 1 September 2026 (UTC).

How many APIs are on PayAPI Market?

There are 100 live APIs listed, covering 609 endpoints in total. 83 of them are settlement-verified, meaning we paid for a real call and checked the response.

What kinds of APIs are there?

  • Data: 48 APIs
  • Finance: 14 APIs
  • Intelligence: 6 APIs
  • Tools: 19 APIs
  • Verification: 13 APIs

What does it cost?

Prices are per request. The cheapest verified API starts at $0.001 a call. You pay only for the calls you make.

How does an agent use this?

The catalogue is machine-readable, so an agent can search it directly:

curl "https://payapi.market/agent/search?q=company+data"
curl "https://payapi.market/agent/get?id=<slug>"

The response gives the base URL, the price and the network for each API. The agent then calls the API, receives an HTTP 402 with a payment challenge, pays it, and retries.

What does verified mean?

It means we sent real money. For each verified API we paid for a call from our own wallet, using an input we chose rather than the provider's advertised example where we could, and checked the response against a public source when one exists.

APIs that are listed but not yet verified are shown as listed, not verified. We do not describe them as verified until we have paid.
