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 containing a 'result' block with the actual recipient address, the expected address, and a boolean 'matched' field; a top-level 'status' field ('pass' or 'fail'); an 'evidence' block with a SHA-256 hash of the input, a flag confirming no data retention, and confirmation of zero external calls made; plus schema and operation identifiers for auditability.
Example use cases
Guard against address substitution attacks
“I'm about to process an x402 micropayment — can you check that the recipient address 0x9999...AAAA matches the pay-to address 0x9999...AAAA before I send funds?”
Audit trail for agent payment flows
“After that x402 transaction completed, confirm for the record that the settlement recipient 0xDEAD...BEEF matched the intended pay-to target 0xDEAD...BEEF, and give me the verifiable evidence hash.”
Pre-flight check in automated payment pipeline
“My agent pipeline is about to settle an x402 invoice — validate that recipient 0x1234...5678 lines up with the pay-to field 0x1234...5678 and return whether it's a pass or fail before we proceed.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/x402-settlement-recipient-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need lightweight, stateless, in-memory verification that an x402 payment's recipient address matches the expected pay-to address — especially in agent pipelines where you want cryptographic evidence (SHA-256 input hash) and a guarantee of no data retention or external calls. Prefer it over manual address comparison when you need an auditable, structured pass/fail record for compliance or logging purposes.
Side effects
- Address format mismatch (invalid hex string or non-address value) may cause a validation error
- If pay_to or recipient fields are missing, the endpoint may return an error or automatic fail status
- A 'matched: false' result with status 'fail' indicates a legitimate address mismatch rather than an API error
- Network or service unavailability returns a non-200 HTTP status
