How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object with a boolean 'matched' field, the actual and expected URLs, a pass/fail status, and an evidence block containing a SHA256 hash of the input and confirmation that no data was retained and no external calls were made. Follows the delx/util-x402-resource-match/v1 schema.
Example use cases
Verify X402 payment delivery
“I just received an x402 resource URL back from a pay-per-result API call. Can you verify that https://api.partner.ai/x402/data/result matches the expected resource https://api.partner.ai/x402/data/result and confirm the delivery was correct?”
Audit agent resource fulfillment
“My AI agent completed an x402 transaction and I want to confirm the resource it was delivered matches what was contracted — expected is https://commerce.delx.ai/api/v1/x402/reports/q1, actual is https://commerce.delx.ai/api/v1/x402/reports/q1. Does it check out?”
Validate resource before releasing funds
“Before my agent finalizes an x402 payment, check whether the actual resource URL https://api.delx.ai/x402/utility/weather matches the expected resource https://api.delx.ai/x402/utility/weather and return verifiable evidence I can log.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/x402-resource-match?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a verifiable, auditable, cryptographically-evidenced check that a resource URL delivered via an x402 payment matches the resource URL that was originally contracted — especially in autonomous agent workflows where delivery accountability matters. Prefer this over naive string comparison when you need an evidence trail (SHA256 hash, no-retention proof) for compliance or dispute resolution in x402-based commerce.
Side effects
- Mismatched URLs return matched:false with status 'fail' rather than an error
- Inputs exceeding 8192 characters may be rejected
- Malformed or non-URL strings may produce unexpected comparison results
- Missing required fields (expected or resource) will result in a validation error
