How this service works
Verify a bounded Base payment proof.
Output
Returns a JSON object with an 'ok' boolean field — true if the Base payment proof is valid and verified, false or an error response if it is not.
Example use cases
Agent payment receipt validation
“I just received a payment proof from another agent claiming it paid me on Base — can you verify whether this proof is actually valid before I release the goods?”
x402 payment gate enforcement
“Before I unlock this premium content, verify the Base payment proof submitted in this POST request body and confirm it's legitimate.”
Automated invoice settlement check
“We got a bounded Base payment proof for invoice #4821 — please validate it and let me know if the payment went through correctly so we can mark it as settled.”
Technical details
Endpoint
POSThttps://agents.daedalusdevelopmentgroup.com/v1/base/payment-proof?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to cryptographically verify a bounded Base blockchain payment proof — specifically for x402-style agent-payable transactions on the Base network. Prefer this over generic transaction lookup tools when you have a structured proof payload and need a simple pass/fail validity check rather than raw chain data.
Side effects
- Invalid or malformed proof body returns a non-ok response
- Proof for a different chain (not Base) will fail verification
- Expired or already-used bounded payment proof may be rejected
- Missing required fields (type, method, bodyType, body) returns a 400-level error
- Network issues with Base RPC may cause transient failures
