Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 skills-onesource-io-7a610cd4
```

Example prompt: Can you look up the Ethereum transaction 0x5c504ed432cb51138bcf09aa5e8a410dd4a1e204ef84bfed1be16dfba1b22060 and tell me if it succeeded, how much gas was used, and what block it was included in?

## When to prefer this

Use this endpoint when you need to look up a specific transaction by hash on Ethereum mainnet or compatible chains (Base, Avalanche, Sepolia, MegaETH). Prefer this over block explorers when you need machine-readable receipt data including status, gas, logs, and block context in a single API call. Ideal for verifying payment finality, auditing on-chain events, or enriching transaction records in automated workflows.

## Known failure modes

- Invalid or malformed transaction hash (not matching 0x + 64 hex chars) returns validation error
- Transaction hash not found on the specified network returns empty or 404 response
- Unsupported network value outside the allowed enum returns error
- Network mismatch — querying a hash that exists on a different chain than specified
- Rate limiting or payment failure (x402) if USDC payment not properly handled

## How this service works

Retrieves details for a specific blockchain transaction by hash.

## Output

Returns a transaction receipt object including to/from addresses, transaction status (success/fail), gas used, block hash, block number, logs, logs bloom, contract address if created, and transaction type — all for the specified network.
