## 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 agentforge-evm-transaction-decoder-5686b5a2
```

Example prompt: Can you decode this Ethereum transaction and tell me in plain English what function was called and what tokens were transferred? The tx hash is 0x4a7f3b2c1d9e8f0a5b6c7d3e2f1a4b8c9d0e7f6a5b4c3d2e1f0a9b8c7d6e5f4a.

## When to prefer this

Use this endpoint when an agent or user needs to understand what a specific EVM transaction did without reading raw hex data. Ideal for post-hoc analysis of on-chain activity, auditing suspicious transactions, debugging smart contract interactions, or explaining DeFi actions to non-technical users. Supports Ethereum, Base, Polygon, Arbitrum, Optimism, and Avalanche. Prefer this over generic block explorers when a structured, machine-readable + human-readable decoded output is needed programmatically.

## Known failure modes

- Transaction hash not found on the specified chain — returns error if the tx doesn't exist or is pending
- Invalid transaction hash format — returns validation error if hash doesn't match 0x + 64 hex chars pattern
- Unknown or unverified contract ABI — decoder may return partial results if the contract is unverified
- Chain mismatch — transaction exists on a different chain than specified
- Network timeout — chain RPC unavailable at time of request

## How this service works

Transaction decoder for agents and users who need to know what a raw EVM transaction actually does: function call, parameters, and token transfers in plain English. Category: data.

## Output

A human-readable breakdown of the transaction including: the contract function that was called, decoded input parameters with labels, token transfer events (sender, recipient, amount, token), and a plain English summary of what the transaction accomplished.
