# OneSource Ethereum Transaction Receipt Lookup

> OneSource Ethereum Transaction Receipt Lookup is a paid API for AI agents from api.onesource.io, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Fetches the on-chain transaction receipt for a given Ethereum or Sepolia transaction hash, including status, gas used, logs, and block details.

## Facts

- Endpoint: GET https://api.onesource.io/api/chain/receipt/%7Bhash%7D
- Price: $0.005/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/onesource-ethereum-transaction-receipt-lookup-e1b3a05e
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_2jGgzDux385aN1NTkup__

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 onesource-ethereum-transaction-receipt-lookup-e1b3a05e
```

Example prompt: Did transaction 0xad7e04119ecd85857728205f5b12e95f0bab8e99f9c2f60be5dc79cfc6a8df1f go through on Ethereum mainnet? I need the receipt — status, gas used, block number, and any logs.

## When to prefer this

Use this endpoint when you need to confirm whether a specific Ethereum or Sepolia transaction succeeded, retrieve gas cost data, find the block it was mined in, or extract event logs from a known tx hash. Prefer this over full node RPC calls when no API key management is desired and pay-per-call USDC micropayments are acceptable.

## Known failure modes

- Invalid hash format (not 0x-prefixed 64-hex-char string) returns validation error
- Transaction hash not found on specified network returns 404 or null result
- Network mismatch (hash exists on mainnet but queried on sepolia) returns not found
- Payment failure via x402/MPP results in 402 Payment Required response
- Node temporarily unavailable returns 503

## How this service works

Two data families for AI agents: live Ethereum mainnet, Sepolia testnet, and Robinhood Chain RPC reads, plus Deepstate on-chain market data (order books, trades, candles, and analytics). Pay per call or use batch/session mode: USDC on Base via x402, or pathUSD/USDC.e on Tempo via MPP. No API key required to start; a flat-rate monthly subscription is also available.

## Output

A JSON object containing the transaction receipt: status (0x1 = success, 0x0 = failure), gas_used, block_number, transaction_hash, effective_gas_price, and a logs array of any events emitted during execution.
