## 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 pocket-network-evm-transaction-explainer-e05551a5 -d '<json body>'
```

Example prompt: Can you explain what this Ethereum transaction did — hash 0x4a1b2c3d4e5f... on chain ID 1 — and let me know if there are any risk flags or suspicious approvals?

## When to prefer this

Choose this endpoint when you need a fast, structured, plain-language breakdown of a specific EVM transaction — especially for DeFi activity, token approvals, or risk screening — and you want deterministic output without setting up an API key or account. Prefer it over raw block explorers when you need machine-readable JSON with risk flags and decoded asset movements rather than raw hex data.

## Known failure modes

- Invalid or unrecognized transaction hash returns an error
- Transaction not yet indexed on the specified chain returns not-found
- Unsupported chain_id returns an unsupported chain error
- Malformed 0x-prefix or incorrect hash length triggers validation error
- Network timeout if the target chain RPC is slow or unavailable

## How this service works

Pay-per-call access to Pocket Network services. No account, no API key.

## Output

A single JSON object containing: a plain-language summary of the transaction's intent, a list of asset movements (tokens, amounts, directions), gas cost details, sender/receiver party info, any token approvals granted, and risk flags (e.g. suspicious patterns, known malicious addresses).
