Delx Commerce — x402 Payment Lifecycle Reconciliation
x402
Delx Commerce — x402 Payment Lifecycle Reconciliation is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-02).
Reconciles and verifies x402 payment lifecycle artifacts (settlement reference, delivery receipt, payment response, and payment requirement) to produce a cryptographic verdict on whether a pay-per-result transaction was correctly completed.

How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
A JSON object containing a top-level 'verdict' (e.g. 'proven'), a 'limitation' disclaimer noting that verdicts are computed from provided artifacts only (no on-chain fetch), and a 'fields' map showing each key payment attribute (payTo, amount, network, resource) with its status ('proven' or otherwise) and the values reported by each artifact (settlement_ref, delivery_receipt, payment_response, payment_requirement).
Example use cases
Post-call payment audit for agent
“After my agent just made a pay-per-result API call using x402, I want to verify the payment completed correctly — can you cross-check the settlement ref, delivery receipt, payment response, and payment requirement to make sure the verdict is proven?”
Dispute resolution for agent micropayment
“I think there's a mismatch between what was required and what was actually paid in this x402 transaction — can you reconcile the payment lifecycle artifacts and tell me which fields show discrepancies?”
Automated payment proof for compliance
“I need a verifiable proof that a USDC payment on Base went through correctly for our records — can you run the lifecycle reconciliation on these four x402 artifacts and give me the full field-by-field verdict?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/lifecycle-reconcile?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent or payment orchestrator needs to verify that an x402 pay-per-result transaction completed correctly, by comparing all four lifecycle artifacts (settlement ref, delivery receipt, payment response, payment requirement) against each other. Prefer this over manual inspection when you need a structured, field-by-field proof verdict for audit, compliance, or dispute resolution — especially within the Delx Commerce / x402 ecosystem on Base or Solana. Note: this endpoint does not fetch on-chain state; it reconciles only the artifacts you supply.
Side effects
- Missing or malformed artifacts produce incomplete field comparisons or a non-proven verdict
- Mismatched values across artifacts (e.g. different amounts) result in a non-proven status for that field
- No on-chain state is fetched, so the verdict reflects only the provided data — not actual blockchain finality
- Private keys or signatures included in input are rejected per bounded metadata rules
- Incomplete input objects may yield partial verdicts with some fields unresolved
