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') indicating the outcome of the specified blockchain transaction.
Example use cases
Confirm payment before fulfilling order
“Before I ship this order, can you verify that the on-chain payment actually landed? The transaction hash is 0x1a2b3c4d5e6f7a8b9c0d1e2f3a4b5c6d7e8f9a0b1c2d3e4f5a6b7c8d9e0f1a2b on Base.”
Debug a failed crypto transfer
“My Ethereum transfer seems stuck — can you look up the outcome of tx hash 0xabcdef1234567890abcdef1234567890abcdef1234567890abcdef1234567890ab and tell me if it succeeded or failed?”
Automated settlement verification for DeFi workflow
“After our smart contract interaction completed, check the transaction result for 0xdeadbeef1234567890abcdef1234567890abcdef1234567890abcdef12345678ab on Base and tell me if it's ready.”
Technical details
Endpoint
POSThttps://x402-gateway-production-1f21.up.railway.app/commerce/tx-outcome?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, machine-payable ($0.001 USDC) way to verify blockchain transaction outcomes on Base or Ethereum. Prefer this over building your own RPC calls when operating within an x402 micropayment context or when you need a simple status check without running a full blockchain node.
Side effects
- Invalid tx_hash format (must match ^0x[a-fA-F0-9]{64}$) returns validation error
- Unknown or pending transaction returns non-ready status
- Unsupported network (only 'base' and 'ethereum' are valid) returns error
- Payment failure via x402 protocol prevents access to the endpoint
- Network RPC timeout or blockchain node unavailability causes lookup failure
