How it works

  1. The agent sends a GET request to the donate endpoint.
  2. The server answers HTTP 402 with the payment requirements.
  3. The agent signs a USDC payment and retries with PAYMENT-SIGNATURE.
  4. The payment is verified and settled, and a thank-you is returned.

Test the x402 connection

Check that the x402 payment endpoint responds. This sends a request without a payment signature, so you should see an HTTP 402 response with the payment requirements.

Or try it with curl

curl -i https://vat.businesspress.io/api/x402/donate
