How payment works

1

Call endpoint

Send a request to any tool endpoint. If payment is required, you get back HTTP 402 with the price and payment details.

2

Sign and retry

Your x402 client signs a USDC payment from your agent's wallet and retries the request with the payment header.

3

Settle and respond

Payment settles on Base, the tool executes, and the response comes back. The whole flow takes seconds.
