## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability x402-web-probe-blockchain-transaction-lookup-hub-europe-germany-391a5ba1
```

Example prompt: Can you look up the status and confirmation count for transaction 0x142d15b73dfbf96c4a75a62079e8a1f4999916229734e0c28feafc752323e599 on the Base network?

## When to prefer this

Choose this endpoint when you need a quick, no-account, pay-per-call transaction lookup on Base or Ethereum and want to avoid setting up API keys with providers like Etherscan or Alchemy. Ideal for lightweight agent workflows that only occasionally need on-chain tx data and benefit from micro-payment pricing via x402.

## Known failure modes

- Invalid or malformed transaction hash returns an error
- Unsupported chain value (anything other than 'base' or 'ethereum') returns a validation error
- Transaction not yet indexed or pending may return incomplete data
- Payment failure via x402 results in HTTP 402 and no data returned
- Network timeout from the Germany probe hub may cause delayed or failed responses

## 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/fail status, gas used, ETH value transferred, and number of confirmations.
