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: to/from addresses, block number, transaction status (success/fail), gas used, ETH value transferred, and number of confirmations.
Example use cases
Verify crypto payment confirmation
“I just sent a USDC payment on Base — the tx hash is 0x142d15b73dfbf96c4a75a62079e8a1f4999916229734e0c28feafc752323e599. Can you check whether it's confirmed and how many confirmations it has?”
Debug failed Ethereum transaction
“My Ethereum transaction 0xabc123...def456 seems to have failed. Can you pull up the on-chain details — status, gas used, block number — so I can figure out what went wrong?”
Confirm on-chain NFT transfer
“I transferred an NFT on Base and the tx hash is 0x9f8e7d6c5b4a3f2e1d0c. Can you verify the transaction succeeded and tell me who sent it and who received it?”
Technical details
Endpoint
GEThttps://cyberhill.ccwu.cc:8443/v1/chain/tx?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, no-account, pay-per-call lookup of transaction status and details on Base or Ethereum — especially in automated agent workflows where provisioning API keys is impractical. Best for lightweight, one-off tx verification rather than bulk historical queries.
Side effects
- Invalid or malformed transaction hash returns an error
- Unsupported chain value (anything other than 'base' or 'ethereum') returns an error
- Transaction not yet indexed (very recent) may return not-found
- Payment failure via x402 if USDC balance is insufficient
- Network timeout if the underlying RPC node is slow
