## 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 tx-origin-phishing-mcp-3a9e6be7 -d '<json body>'
```

Example prompt: Check this raw transaction data for any tx.origin phishing vulnerabilities or suspicious smart contract patterns: 0x4a22...d9f1

## When to prefer this

Choose this endpoint when you specifically need to detect tx.origin-based phishing vulnerabilities in Ethereum or EVM-compatible smart contract transactions. It is purpose-built for this attack class rather than general smart contract auditing or broad malware scanning.

## Known failure modes

- Invalid or malformed transaction data string returns an error response
- Empty or missing 'data' field causes a 400-level validation failure
- Ambiguous transaction format may yield inconclusive detection results
- Network timeout or service unavailability returns a 5xx error
- Unsupported chain or encoding format may not be recognized

## How this service works

## Output

Returns a structured analysis of the submitted transaction data indicating whether tx.origin-based phishing patterns are present, including risk classification, detected attack vectors, and a confidence or severity assessment.
