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.

Returns a JSON object with the transaction's sender and recipient addresses, block number, success/failure status, gas used, ETH value transferred, and number of confirmations on the specified chain.
Example use cases
Verify crypto payment confirmation
“Did this transaction go through on Base? Hash is 0x142d15b73dfbf96c4a75a62079e8a1f4999916229734e0c28feafc752323e599 — I need to know if it succeeded and how many confirmations it has.”
Debug failed Ethereum transaction
“I have an Ethereum transaction hash 0xabc123... and I think it might have failed — can you look it up and tell me the status, gas used, and what block it landed in?”
Audit on-chain payment for accounting
“For our records, can you pull the full details for Base transaction 0x142d15b73dfbf96c4a75a62079e8a1f4999916229734e0c28feafc752323e599 — I need the sender, receiver, value in ETH, and block number.”
