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 sender (from), recipient (to), block number, success/failure status, gas used, ETH value transferred, and number of confirmations.
Example use cases
Verify a crypto payment received
“I just got told a payment was sent to me on Base — can you check transaction 0x142d15b73dfbf96c4a75a62079e8a1f4999916229734e0c28feafc752323e599 and confirm it succeeded and how many confirmations it has?”
Debug a failed DeFi transaction
“My DeFi swap on Ethereum might have failed — can you pull up the details for tx hash 0xabc123...def456 on Ethereum and tell me the status and gas used?”
Audit smart contract execution
“I need to audit whether our smart contract call went through correctly on Base — look up transaction 0x9f8e7d6c5b4a3210fedcba9876543210fedcba9876543210fedcba9876543210 and give me the block number, from/to addresses, and confirmation count.”
Technical details
Endpoint
GEThttps://dex12345.ccwu.cc:8443/v1/chain/tx?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, pay-per-call transaction lookup on Base or Ethereum without setting up an RPC node or API key. Ideal for one-off verifications, automated payment auditing, or lightweight agents that need blockchain data without committing to a subscription. Choose it over full-node queries when cost-per-call micropayment (0.002 USDC) is preferable to monthly API plans.
Side effects
- Invalid or malformed tx hash returns an error
- Unsupported chain name (only 'base' or 'ethereum' accepted)
- Transaction not yet indexed if very recent
- Payment failure via x402 if USDC balance is insufficient
- Network timeout if the RPC node is unreachable
