How this service works
Pay-per-call website uptime/latency/TLS checks and fetch-to-Markdown, measured from Hub Europe (Germany). USDC on Base via x402. No account or API key.
Output
Returns a JSON object containing the transaction's sender (from), recipient (to), block number, status (success/fail), gas used, ETH value, and number of confirmations.
Example use cases
Verify crypto payment receipt
“I need to confirm that a USDC payment I sent actually went through — can you check transaction 0x142d15b73dfbf96c4a75a62079e8a1f4999916229734e0c28feafc752323e599 on Base and tell me if it was successful and how many confirmations it has?”
Debug failed on-chain transaction
“Something went wrong with my Ethereum transaction 0xabc123...def456 — can you look it up and tell me whether it failed, what status it has, and how much gas it consumed?”
Audit transaction sender and recipient
“Can you pull up the details for Base transaction 0x142d15b73dfbf96c4a75a62079e8a1f4999916229734e0c28feafc752323e599 and tell me the from and to addresses, the block it landed in, and the ETH value transferred?”
Technical details
Endpoint
GEThttps://bluebirds.ccwu.cc:8443/v1/chain/tx?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, pay-per-call lookup of a specific transaction hash on Base or Ethereum without setting up an account or API key. It is ideal for ad-hoc verification of payment status, gas consumption, or confirmation count in agent workflows that require on-chain proof.
Side effects
- Invalid or malformed transaction hash returns an error
- Transaction hash not found on the specified chain
- Unsupported chain value (only 'base' or 'ethereum' accepted)
- Network timeout or RPC node unavailability
- Payment failure via x402 prevents the request from being processed
