How this service works
Deterministic compliance verification (IBAN, sanctions, onchain address) with XDR-1 signed receipts, plus Ethereum chain-data endpoints. Paid per call via x402 on Base (USDC).
Output
Returns a JSON object containing the transaction receipt for the specified Ethereum tx hash, including success/failure status, block number, gas used, logs emitted, and the network identifier ('ethereum').
Example use cases
Confirm DeFi swap execution
“I just submitted a swap on Uniswap — transaction hash is 0x4f9a…c231. Can you grab the receipt and tell me if it confirmed, what block it's in, and how much gas it burned?”
Audit NFT mint on-chain
“We minted an NFT batch and the tx hash is 0x7d3e…88fa. Pull the transaction receipt so I can confirm the mint went through and see the event logs.”
Verify cross-chain bridge deposit
“My bridge deposit transaction is 0x2b17…55dc on Ethereum — fetch the receipt and confirm it was successful so I can check when the funds should arrive on the other side.”
Technical details
Endpoint
GEThttps://verify.code402.dev/v1/chain/tx-receipt/%7Bhash%7D?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a pay-per-call, no-subscription approach to fetching Ethereum transaction receipts — especially in agentic or automated pipelines where you want to avoid monthly API keys. Prefer it over Etherscan or Alchemy free tiers when you need cryptographically signed receipts (XDR-1) or when operating within an x402-native payment flow on Base.
Side effects
- Invalid or malformed transaction hash returns an error response
- Transaction hash not found on Ethereum mainnet (e.g. wrong network) returns not-found error
- Payment failure via x402 (insufficient USDC balance or misconfigured payment header) blocks the request
- Network or RPC timeout results in a service error
- Hash for a pending/unconfirmed transaction may return empty or null receipt
