## 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 x402-chain-tools-get-base-transaction-receipt-2a92099f -d '<json body>'
```

Example prompt: Can you check whether transaction 0x3a1b2c4d5e6f7a8b9c0d1e2f3a4b5c6d7e8f9a0b1c2d3e4f5a6b7c8d9e0f1a2b on Base Mainnet was confirmed and successful?

## When to prefer this

Use this endpoint when you need the full execution receipt and success status for a specific Base Mainnet transaction hash. Prefer this over the basic transaction lookup endpoint when you need to confirm whether the transaction actually succeeded (not just that it was submitted), or when you need the full receipt object for further processing.

## Known failure modes

- Invalid or malformed transaction hash (not matching 0x + 64 hex chars) returns a validation error
- Transaction not yet mined returns confirmed: false and receipt_found: false with receipt: null
- Network timeout or RPC unavailability may return an error or partial response
- Hash for a transaction on a different network (not Base Mainnet) may return receipt_found: false

## How this service works

Get a Base transaction receipt and execution status.

## Output

Returns a JSON object with: ok (boolean), the queried hash, network identifier (eip155:8453 for Base Mainnet), receipt (full receipt object or null), success (boolean or null indicating execution outcome), confirmed (boolean), and receipt_found (boolean).
