How x402 Micropayments Work

1

Request endpoint

Your agent calls any paid endpoint. The server returns HTTP 402 with payment requirements in the WWW-Authenticate header.

2

Submit USDC payment

The x402 client library pays the required USDC amount on Base via the facilitator (x402.org). Your wallet is charged automatically.

3

Retry with proof

The client retries the original request with the X-Payment header containing payment proof. The server verifies and returns the data.
