Testnet only. Signs locally in your browser — never sent to our server.

Or wire it up yourself

Same endpoint, same receipt — from an agent instead of a browser tab.

curl -i https://micropay-test-suite.netlify.app/api/test-payment
# → 402 Payment Required
# (x402 payment terms in the response headers/body)

# Your x402 client signs and retries automatically:
curl -i https://micropay-test-suite.netlify.app/api/test-payment \
  -H "X-PAYMENT: <signed-payment-header>"
# → 200 OK + receipt JSON
