PayAPI Market

A job, then a payment

Give your agent a job and a budget.

It finds the right API, pays per call in USDC, and gets clean output back with an on-chain receipt.

Last updated: 14 November 2026

A simple mental model

  1. Job. The outcome you want. A file as Markdown, an article pulled out of a page, a diagram drawn.
  2. Budget. The USDC you put in a wallet, and the most you will let one call cost.
  3. Receipt. Structured results come back. The payment is a public USDC transfer you can open.

One afternoon, 9 cents

On 14 November 2026 PayAPI tested three of its own first-party house agents. Each call was Base USDC, paid to PayAPI's House wallet. These are our agents, not a sample of other providers. For each line, settlement-verified means that one paid route: PayAPI paid it from its own wallet, and the Basescan link is the on-chain receipt.

Frequently asked questions

What does my agent do with a job and a budget?

It searches PayAPI for free over MCP or over plain HTTP, calls the provider's API, and pays that call in USDC when the price is inside the budget you set. The provider returns structured results. The USDC transfer is the on-chain receipt.

Do I need an account or an API key?

No. There is no buyer account and no API key. The agent pays the provider's wallet directly.

What did the 14 November 2026 house agent test cost?

Three of PayAPI's own first-party house agents, paid in Base USDC to PayAPI's House wallet. File to Markdown was $0.04, Article Extract was $0.02, and Diagram Render was $0.03. The total was 9 cents. Each Basescan link on this page is the receipt for that route.

What does settlement-verified mean on this page?

Settlement-verified means one paid route with an on-chain receipt. PayAPI paid that route from its own wallet, got a real result back, and linked the transaction. It covers that route. It does not cover the other routes on a listing, and it does not mean the rest of the catalogue has been paid.

What does it cost to list an API?

Free to list, PayAPI takes 0% of each job. The buyer pays the provider's own per-call price in USDC.
