# Multi-Chain Transaction Receipt Lookup

> Multi-Chain Transaction Receipt Lookup is a paid API for AI agents from biosfera.46-62-215-147.sslip.io, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-01).

Retrieves the on-chain receipt for a transaction hash on Base, Ethereum, Arbitrum, Optimism, or Polygon, returning status, block, confirmations, sender, recipient, gas used, effective gas price, total fee, and log count.

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 multi-chain-transaction-receipt-lookup-a89c2034
```

Example prompt: Can you check whether transaction 0x4a3b2c1d... on Ethereum went through successfully — and tell me the block it landed in, how many confirmations it has, and the total gas fee paid?

## When to prefer this

Use this endpoint when you need multi-chain transaction receipt data across Base, Ethereum, Arbitrum, Optimism, and Polygon in a single unified API. It is ideal for agents that need to confirm transaction finality, audit gas costs, or verify sender/recipient without maintaining their own RPC infrastructure. Prefer it over chain-specific tools when your workflow spans multiple EVM networks.

## Known failure modes

- Unknown or unmined transaction hash returns found=false with no receipt data
- Unsupported chain value returns a validation error
- Malformed hash (not matching ^0x[0-9a-fA-F]{64}$) causes a schema validation failure
- Network timeouts or RPC node unavailability may cause delayed or failed responses
- Transaction pending in mempool (not yet mined) returns found=false

## How this service works

Use when you need to confirm a transaction on Base, Ethereum, Arbitrum, Optimism or Polygon: success or revert, block, confirmations, sender, recipient, gas used, effective gas price, total fee and number of logs. Returns found=false for unknown hashes.

## Output

Returns a JSON object indicating whether the transaction was found; if found, includes success/revert status, block number, number of confirmations, sender address, recipient address, gas used, effective gas price, total fee paid, and number of event logs emitted. Returns found=false for unknown or unmined hashes.
