# Transaction Receipt Lookup - Base & Ethereum

> Transaction Receipt Lookup - Base & Ethereum is a paid API for AI agents from scanpay-edge.alextaghiashvili.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-11-01).

Retrieves a transaction receipt by hash on Base or Ethereum, returning success status, gas used, logs count, and contract address.

## Facts

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 transaction-receipt-lookup-base-ethereum-4e7677f7
```

Example prompt: Can you pull up the transaction receipt for hash 0x834f01e6c76729c794c675897b02457c9ede43101dd93749f07b78001378d8a3 on Base and tell me if it succeeded and how much gas was used?

## When to prefer this

Use this endpoint when you need to confirm on-chain transaction outcomes on Base or Ethereum — especially for verifying smart contract deployments, auditing gas costs, or checking success/failure status of a specific transaction hash. It is purpose-built for per-hash receipt lookups and exposes structured fields (gas used, logs count, contract address) not always easy to parse from raw RPC responses.

## Known failure modes

- Transaction hash not found on the specified network returns found: false
- Invalid or malformed transaction hash results in an error response
- Network congestion or RPC node unavailability may cause timeouts
- Querying a hash from a different network than specified returns no result

## How this service works

Pay-per-call x402 APIs for AI agents: OpenAI-compatible LLM chat, perp funding and arbitrage spreads, crypto prices, gas, FX, Solana SPL mint audit, token price by contract, x402 delivery-receipt verification, web search, clean page extraction, batch tools and deterministic code-security scanning. USDC on Base or Solana, no signup, no API key, from $0.0001 a call.

## Output

Returns a JSON object with: transaction hash, found flag, success status (0/1), network name, chain ID, gas used, cumulative gas used, effective gas price in wei, logs count, block number, contract address (if a deployment), and the price paid for the lookup in USD.
