What is on PayAPI Market right now: 72 verified APIs for AI agents

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 2026-08-23.

How many APIs are on PayAPI Market?

There are 89 live APIs listed, covering 585 endpoints in total. 72 of them are settlement-verified, meaning we paid for a real call and checked the response.

What kinds of APIs are there?

  • Data: 45 APIs
  • Finance: 12 APIs
  • Intelligence: 6 APIs
  • Tools: 18 APIs
  • Verification: 8 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 the provider did not advertise, and checked the response against the original public source where 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.
