How this service works
Machine-payable x402 utilities for hashing, Base64, UUID generation, unit and timezone conversion, realtime crypto market data, webpage/document extraction, URL-to-Markdown, metadata, RAG ingestion and deterministic website change detection.
Output
Returns a JSON object with a status field (e.g. 'ready') and potentially a full receipt or confirmation details for the given USDC transaction hash, indicating whether the payment is confirmed on-chain.
Example use cases
Confirm payment before delivering service
“I just sent a USDC payment and need to verify it went through — can you fetch the receipt for tx hash 0xabc123...def456 so I can confirm it's ready before I proceed?”
Audit trail for agent-initiated payment
“My agent made a payment on my behalf. Pull the USDC receipt for transaction 0x1a2b3c4d5e6f7a8b9c0d1e2f3a4b5c6d7e8f9a0b1c2d3e4f5a6b7c8d9e0f1234 so I can log it for accounting.”
Dispute resolution evidence gathering
“A vendor says they never received payment, but I have a tx hash. Can you retrieve the on-chain USDC receipt for 0xdeadbeef1234567890abcdef1234567890abcdef1234567890abcdef12345678 to show them proof?”

Endpoint
POSThttps://x402-gateway-production-1f21.up.railway.app/commerce/usdc-receipt?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically verify or retrieve a receipt for a specific USDC on-chain payment identified by its transaction hash. Prefer this over manual blockchain explorers when automating payment confirmation flows in agent pipelines.
Side effects
- Invalid tx_hash format (must be 0x followed by 64 hex characters) returns a validation error
- Transaction hash not found on-chain returns an error or empty result
- Network/gateway downtime returns a 5xx error
- Transaction is still pending and not yet finalized may return a non-ready status
