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 with the transaction's to/from addresses, block number, success/failure status, gas used, ETH value transferred, and number of confirmations for the specified tx hash on Base or Ethereum.
Example use cases
Verify crypto payment settlement
“I just received a payment on Base with tx hash 0x142d15b73dfbf96c4a75a62079e8a1f4999916229734e0c28feafc752323e599 — can you confirm it succeeded and tell me how many confirmations it has?”
Debug a failed Ethereum transaction
“This Ethereum transaction 0xabc123... seems to have failed — can you look it up and tell me its status, the gas used, and what block it landed in?”
Audit on-chain transfer details
“For compliance purposes, I need the sender address, receiver address, value, and block number for Base transaction 0x142d15b73dfbf96c4a75a62079e8a1f4999916229734e0c28feafc752323e599.”
Technical details
Endpoint
GEThttps://arandar.ccwu.cc:8443/v1/chain/tx?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need quick, pay-per-call blockchain transaction lookups on Base or Ethereum without setting up an RPC node, API key, or account. Ideal for agents that occasionally need to verify transaction finality, check gas costs, or audit on-chain transfers, especially when operating from a European region. Not suited for high-frequency polling (use a dedicated node) or chains other than Base and Ethereum.
Side effects
- Invalid or malformed tx hash returns an error
- Transaction not yet indexed may return not-found or pending status
- Unsupported chain value (not 'base' or 'ethereum') causes validation failure
- Network or payment gateway timeout results in no response
- x402 payment failure blocks the request from being processed
