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 containing the transaction's to and from addresses, block number, success/failure status, gas used, ETH value transferred, and number of confirmations.
Example use cases
Verify crypto payment receipt
“I just sent a payment on Base — can you check transaction 0x142d15b73dfbf96c4a75a62079e8a1f4999916229734e0c28feafc752323e599 and confirm it went through and has at least 5 confirmations?”
Debug failed Ethereum transaction
“Can you pull up the details on this Ethereum transaction hash 0x142d15b73dfbf96c4a75a62079e8a1f4999916229734e0c28feafc752323e599 — I need to know if it failed and what the gas used was.”
Audit on-chain transfer details
“For our records, look up Base transaction 0x142d15b73dfbf96c4a75a62079e8a1f4999916229734e0c28feafc752323e599 and give me the from address, to address, value transferred, and block number.”
Technical details
Endpoint
GEThttps://webthree.ccwu.cc:8443/v1/chain/tx?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, no-account-required transaction lookup on Base or Ethereum and are comfortable paying $0.002 USDC per call via x402. Prefer this over free block explorers when operating in an automated agent context that needs structured JSON output rather than HTML scraping.
Side effects
- Invalid or malformed transaction hash returns an error
- Unsupported chain name (not 'base' or 'ethereum') returns a validation error
- Transaction not yet indexed or very recent may return not-found
- Network timeout if the RPC node is slow
- Payment failure via x402 if USDC balance is insufficient
