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 to/from addresses, block number, transaction status (success/failure), gas used, ETH value transferred, and number of confirmations for the queried transaction hash.
Example use cases
Verify crypto payment confirmation
“I just sent a payment on Base with tx hash 0x142d15b73dfbf96c4a75a62079e8a1f4999916229734e0c28feafc752323e599 — can you check if it's confirmed and how many confirmations it has so far?”
Audit DeFi transaction gas costs
“Pull the details for Ethereum transaction 0x142d15b73dfbf96c4a75a62079e8a1f4999916229734e0c28feafc752323e599 and tell me the gas used and the block it landed in.”
Debug failed on-chain transaction
“This Base transaction 0x142d15b73dfbf96c4a75a62079e8a1f4999916229734e0c28feafc752323e599 might have failed — can you fetch its status and let me know if it succeeded or reverted?”
Technical details
Endpoint
GEThttps://rubycom.ccwu.cc:8443/v1/chain/tx?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a pay-per-call, no-account-required way to look up blockchain transaction details on Base or Ethereum. Ideal for agents that only occasionally need on-chain tx data and don't want to manage RPC credentials or API keys. Not suitable for high-volume batch lookups or chains other than Base/Ethereum.
Side effects
- Invalid or malformed transaction hash returns an error
- Unsupported chain name (anything other than 'base' or 'ethereum') causes a bad request
- Transaction not yet indexed if very recent — may return not-found
- Network or payment failure if USDC payment via x402 is not completed
- Rate limiting or node unavailability on the backend RPC provider
