How this service works
Use when testing an x402 client or wallet end-to-end: pay $0.01 USDC and get a signed JSON receipt proving payment settled. Example input: GET /x402/v1/protected-demo. Example output: {"ok":true,"paid":true,"network":"eip155:8453","payer":"0x…","txHash":"0x…"}
Output
A JSON object with fields: ok (boolean), paid (boolean), network (e.g. 'eip155:8453' for Base), payer (the paying wallet address as 0x…), and txHash (the onchain transaction hash confirming settlement). Confirms end-to-end that the x402 micropayment was accepted and recorded on Base.
Example use cases
End-to-end x402 client smoke test
“Run a quick end-to-end test of my x402 payment client — pay the $0.01 USDC demo fee and show me the signed JSON receipt with the txHash so I know the full flow is working.”
Wallet integration verification before launch
“Before I ship my new wallet's x402 support, I want to make one real micropayment to a live protected endpoint — hit the Genesis Token Labs demo, pay the one-cent USDC charge, and confirm I get back a valid payment receipt.”
Agent payment capability proof
“My AI agent needs to prove it can autonomously pay x402-gated APIs — have it pay the $0.01 USDC protected demo on Base and return the receipt showing the payer address and transaction hash.”
Technical details
Endpoint
GEThttps://api.genesistokenlabs.com/x402/v1/protected-demo?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a cheap, real, end-to-end test of an x402 payment client or wallet integration against a live Base mainnet endpoint. It is purpose-built for developer verification and agent smoke-testing of the x402 protocol — not for production data retrieval. Prefer it over mock environments when you need an actual onchain txHash as proof of settlement.
Side effects
- Insufficient USDC balance — payment cannot be fulfilled if the wallet lacks $0.01 USDC
- Invalid or missing x402 payment header — returns 402 Payment Required with no receipt
- Unsupported network — payment on a chain other than Base (eip155:8453) may be rejected
- Transaction not yet confirmed — onchain latency may delay a valid txHash being available
- Malformed request method — only GET, HEAD, DELETE are accepted; POST returns an error
