## 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 stall-row-transaction-decoder-97ad881f -d '<json body>'
```

Example prompt: Can you decode transaction 0x4a3b2c1d... on Base and tell me in plain English who sent it, who received it, how much ETH moved, whether it succeeded, and what ERC-20 tokens were transferred?

## When to prefer this

Use this endpoint when an agent needs to explain, verify, or audit a specific Base network transaction in human-readable terms before taking action — especially when ERC-20 token flows or method identification matter. Prefer over a raw block explorer when a structured JSON response and plain-English summary are needed programmatically.

## Known failure modes

- Invalid or malformed transaction hash returns an error
- Transaction hash not found on Base network (wrong chain or hash)
- Unrecognized function selector returns raw selector without method name
- Pending transactions may not yet be decodable
- Network or RPC timeouts on busy blocks

## How this service works

Decode one Base transaction into plain English: sender, receiver, ETH value, status, the known method behind the selector, every ERC-20 transfer it made, and a one-sentence summary. Use this when an agent needs to explain or verify what a transaction actually did before acting on it.

## Output

Returns the decoded transaction details including sender address, receiver address, ETH value transferred, transaction status (success/fail), the human-readable method name behind the function selector, a list of every ERC-20 transfer event with token, amount, from, and to, and a concise one-sentence plain-English summary of what the transaction did.
