How this service works
Verify x402 delivery after payment. Check Base USDC settlement receipt, exact payTo/amount, HTTP delivery status and return PROVEN, INCOMPLETE or CONFLICT.
Output
Returns an attestation verdict of PROVEN (payment settled correctly and HTTP delivery succeeded), INCOMPLETE (payment or delivery not yet confirmed), or CONFLICT (mismatch between on-chain settlement and delivery status), along with supporting details about the settlement receipt, payTo/amount comparison, and HTTP response code.
Example use cases
Confirm agent purchase was fulfilled
“I just had my AI agent make an x402 micropayment to get a data feed — transaction hash is 0xdef456, payTo is 0xProvider789, atomic amount was 3000, and the server returned HTTP 200. Can you verify the delivery was actually proven on-chain?”
Detect payment-delivery conflict
“Something seems off — I paid via x402 (tx hash 0xaaa111, payTo 0xMerchant222, amount 3000 atomic) but the endpoint returned a 402 status. Can you check whether that counts as CONFLICT or INCOMPLETE?”
Audit x402 transaction for compliance
“For our audit trail, please check transaction 0xbbb333 where we expected payTo 0xVendor444 and atomic USDC amount 3000 — the HTTP response was 200 — and tell me if delivery is PROVEN, INCOMPLETE, or CONFLICT.”
Technical details
Endpoint
GEThttps://ozeejewwpjmabshxyitc.supabase.co/functions/v1/telago-x402-delivery-attestor-v1/verify-x402-delivery-after-payment?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to cryptographically attest that an x402 HTTP micropayment on Base USDC resulted in actual content delivery — especially for agent workflows that require proof-of-delivery before releasing funds or logging compliance records. Prefer this over manual receipt checks when you need a structured PROVEN/INCOMPLETE/CONFLICT verdict that can be acted on programmatically.
Side effects
- Transaction hash not found on Base network — returns INCOMPLETE or error
- payTo address mismatch between expected and on-chain — returns CONFLICT
- Amount mismatch between expectedAmountAtomic and settled amount — returns CONFLICT
- HTTP response status indicates non-delivery (e.g. 402, 500) — returns INCOMPLETE or CONFLICT
- Invalid or malformed transaction hash — returns validation error
- Network latency causing unconfirmed settlement — returns INCOMPLETE
