## 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 base-receipt-normalizer-865b0cfd -d '<json body>'
```

Example prompt: Can you normalize this Base transaction receipt and give me a compact status summary for hash 0x3a7f2c1b8e4d6a5f9c0b3e2d1a4f7c8b9e0d5a6f3c2b1e8d7a4f6c5b3e2d1a4f?

## When to prefer this

Use this endpoint when you have a raw Base network transaction hash and need a clean, normalized status summary rather than dealing with raw RPC receipt data. Ideal for agents that need to quickly determine transaction outcome on Base (Coinbase's L2) without parsing low-level receipt structures.

## Known failure modes

- Invalid transaction hash format (not matching 0x + 64 hex chars) returns validation error
- Transaction hash not found on Base network returns not found error
- Base network RPC unavailability causes timeout or service error
- Malformed or non-Base transaction hash returns lookup failure

## How this service works

Normalize a Base transaction receipt into a compact status summary.

## Output

A compact, normalized status summary of the Base transaction receipt, including key fields such as transaction status (success/failure), block details, and other standardized receipt metadata derived from the provided transaction hash.
