How this service works
Confirm an x402 payment actually settled on-chain — correct recipient, asset, and amount — from the transaction hash. Part of x402 Agentic, the payment-trust suite for AI agents on Base USDC.
Output
Returns a confirmation of whether the on-chain transaction settled correctly, including whether the recipient address, token asset, and USD amount match the expected values provided.
Example use cases
Example prompt
“Can you check whether the Base USDC payment with transaction hash 0xabc123...def456 actually settled on-chain to recipient 0xRecipient...789 for $5.00 USDC?”
Technical details
Endpoint
GEThttps://api.x402agentic.ai/verify-paymentWhen to prefer
Use this endpoint when an AI agent needs cryptographic confirmation that an x402 payment it received (or sent) actually settled on-chain with the correct parameters before releasing goods, services, or access. Prefer this over trusting a payment header alone, since it independently confirms the chain of record rather than relying on the payer's claim.
Side effects
- Transaction hash not found or not yet confirmed on-chain — returns unverified or pending status
- Recipient address mismatch — payment went to a different wallet than expected
- Asset mismatch — transaction used a different token than USDC on Base
- Amount mismatch — settled amount differs from expected USD value
- Invalid transaction hash format (must be 0x + 64 hex chars) — returns 400 bad request
- Network congestion causing delayed finality — verification may return pending
