## 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 blockchain-money-map-transaction-decoder-dfe99cf5 -d '<json body>'
```

Example prompt: Can you decode this Ethereum transaction and tell me in plain English what happened — what moved, who sent it, and where it went? The hash is 0x4e3a1b2c9f8d7e6a5b4c3d2e1f0a9b8c7d6e5f4a3b2c1d0e9f8a7b6c5d4e3f2a.

## When to prefer this

Choose this endpoint when you need a plain-English narrative explanation of what a specific EVM transaction did — particularly useful for non-technical users, compliance reporting, or when an AI agent needs to communicate on-chain activity in natural language. Prefer this over raw RPC calls or block explorers when interpretability and readability matter more than raw data, and when you need support across Ethereum, Base, Polygon, Arbitrum, and Optimism in one unified API.

## Known failure modes

- Invalid or malformed transaction hash returns an error
- Transaction hash not found on the specified chain
- Chain mismatch — hash exists on a different network than specified
- Network timeout if the specified chain's RPC is slow
- Notes field exceeding 1200 characters rejected
- Missing both hash and transactionHash fields returns validation error
