How this service works
Paid x402 diagnostics. Unpaid paid-SKU requests return HTTP 402 with eip3009 extras. Facilitator: OpenX402 only.
Output
A JSON object containing the SKU identifier ('agentattest'), a human-readable title ('Agent Attest'), the price ('$0.20'), and a diagnostic note confirming the paid response shape. Unpaid requests return HTTP 402 with EIP-3009 payment details instead.
Example use cases
Verify agent x402 payment integration
“Can you hit the Agent Attest endpoint and confirm my agent can successfully pay and receive the attestation response? I want to make sure the x402 + EIP-3009 flow works before I build on top of it.”
Debug HTTP 402 facilitator setup
“I'm getting HTTP 402 errors when my agent tries to call paid APIs. Can you run the OpenClaw agentattest diagnostic with OpenX402 as the facilitator so we can see if the payment is settling correctly?”
Validate USDC micropayment capability
“Test that my agent wallet can actually pay $0.20 USDC through the x402 protocol by calling the Agent Attest endpoint and showing me the confirmed SKU and price in the response.”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/agentattest?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to verify that an AI agent's x402 HTTP payment stack is correctly configured end-to-end, specifically when using the OpenX402 facilitator and EIP-3009 transfer authorization. It is not a production data service — its primary value is as a live payment-gated diagnostic probe.
Side effects
- HTTP 402 returned if payment header is missing or invalid — response includes EIP-3009 extras for retry
- Payment rejected by OpenX402 facilitator if wrong facilitator is used — only OpenX402 is supported
- Malformed or missing authorization signature causes payment failure
- Network timeout if USDC settlement confirmation is slow
