# skills.onesource.io Ethereum Transaction Lookup

> skills.onesource.io Ethereum Transaction Lookup is a paid API for AI agents from skills.onesource.io, paid per call via x402, $0.008000/call, status unknown (last checked 2026-09-14).

Fetches on-chain transaction details and receipt data for a given transaction hash on Ethereum mainnet, returning decoded metadata, block info, and execution receipt fields.

## 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-6ec27de4
```

Example prompt: Can you pull up the full on-chain details and execution receipt for Ethereum transaction 0x88df016429689c079f3b2f6ad39fa052532c56795b733da78a91ebe6a713944b on mainnet — I need the status, gas used, block number, and sender/receiver addresses.

## When to prefer this

Use this endpoint when you need to inspect a specific Ethereum mainnet transaction by its hash and want decoded receipt data including status, gas, block info, and logs — especially in agentic workflows where you need to verify transaction outcomes or extract on-chain execution details without running your own Ethereum node.

## Known failure modes

- Invalid transaction hash format (not 0x + 64 hex chars) — returns validation error
- Transaction hash not found on Ethereum mainnet — returns 404 or empty result
- Network parameter set to unsupported value — returns validation error
- RPC node timeout or Ethereum node unavailability — returns 503 or timeout error
- Payment not provided or insufficient — returns 402 Payment Required

## How this service works

Fetches details for a specific blockchain transaction by hash.

## Output

Returns a JSON object containing the transaction receipt with fields including: to/from addresses, transaction status (success/fail), gas used, block hash, block number, logs, logsBloom, contract address (if deployment), transaction type, and other decoded metadata about the on-chain execution.
