Verified x402 endpoint check

Coming soon. Not on sale yet.

Checks start once our test wallet is set up and funded. Until then we don’t take payment for this. Please don’t send USDC for it. Want to know when it opens? Email us.

What it will test

  1. An unpaid request returns HTTP 402 with valid x402 payment requirements (price, network, asset, pay-to).
  2. The requirements match what your listing says (network, token, price).
  3. A real test payment from our wallet is accepted and settles on-chain.
  4. The paid request returns a successful response (2xx) with a payment-response header.

Planned terms

  • Planned price: $19 USDC, one-off, payable on Base or Solana. The price is confirmed when the check opens.
  • A written report with the request, the 402 response, the settlement transaction and the result.
  • Pass: an “Endpoint checked on YYYY-MM-DD” note on your listing. Fail: the report, plus one free re-test within 30 days.
  • A point-in-time technical check, not an endorsement. It says nothing about data quality, uptime, security or your business, and it never changes rankings.

Meanwhile you can check any endpoint yourself: request it without paying and decode the PAYMENT-REQUIRED header (see what is x402). Want your tool listed? Submit it free.
