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 result block containing chain_id, a base_chain boolean, amount_match boolean, and recipient_match boolean; plus a status field ('pass' or 'fail'), an operation identifier, and an evidence block with retained=false, the SHA-256 hash of the input, and external_calls count — enabling fully verifiable, auditable payment matching without data retention.
Example use cases
Pre-release payment verification for e-commerce
“A customer just sent a USDC payment on Base chain ID 8453. Before I ship the item, verify that the recipient is 0xSeller123 and the raw amount is 5000000 — both match what we invoiced.”
Agent-to-agent payment settlement check
“My agent just claimed it paid another agent 2000000 raw USDC on Base chain 8453. Can you confirm the payment went to 0xAgentWallet456 and the amount matches 2000000 before I mark the task complete?”
Subscription renewal validation
“We received a renewal payment on Base — chain ID 8453, from 0xSubscriber789, raw amount 10000000. Check that both the recipient 0xOurTreasury and the amount match what the subscription contract expects so I can extend their access.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/base-usdc-payment-match?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-use, no-signup preflight check to confirm that a Base chain USDC payment's recipient and amount match expected values before triggering downstream actions. It is ideal for agent pipelines where verifiable, tamper-evident evidence (SHA-256 input hash, no data retention) is required and you do not want to run a full on-chain query yourself. Prefer it over general EVM RPC calls when auditability and simplicity matter more than raw chain access.
Side effects
- Mismatched recipient address returns recipient_match: false with status indicating failure
- Mismatched amount returns amount_match: false
- Invalid or unsupported chain_id may return an error or base_chain: false
- Malformed address strings or non-numeric amount_raw may cause validation errors
- Network or service unavailability returns HTTP 5xx
