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: the input status and whether it was accepted, the list of accepted statuses, a pass/fail status field, an operation identifier ('delivery_contract:x402_delivery_status_check'), and a cryptographic evidence block with an input SHA-256 hash, confirmation of no data retention, and zero external calls made during processing.
Example use cases
Verify payment-gated content delivery
“I just got a status 200 back from a paid API call — can you check if that counts as a successful x402 delivery, with accepted statuses being 200 and 201?”
Debug a failed x402 delivery claim
“My x402 payment went through but the response came back as status 204 — check if that's in the accepted delivery statuses of 200 and 201, and show me the evidence.”
Validate delivery before releasing funds
“Before we release payment, check whether status code 202 is an accepted delivery status given our accepted list of 200, 201, and 202 — I need the full verifiable result.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/x402-delivery-status-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a verifiable, tamper-evident check of whether an HTTP status code qualifies as a successful delivery within the x402 micropayment protocol — particularly when you need cryptographic evidence (SHA-256 input hash, no-retention proof) for auditing or dispute resolution. Prefer this over a local if-statement check when you need an on-chain-verifiable or third-party-auditable delivery confirmation.
Side effects
- Invalid or missing 'status' field returns a validation error
- Accepted statuses array exceeding 256 items is rejected
- Non-integer status codes cause schema validation failure
- Empty accepted_statuses array results in accepted=false for any input
