Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 defi-shield-hazel-vercel-app-937f04ff -d '<json body>'
```

Example prompt: Can you run a deployer forensics check on the wallet 0x3fC91A3afd70395Cd496C647d5a6CC9D4B2b7FAD — I want to see its full contract deployment history, any scam flags, and its reputation score before I interact with this protocol.

## When to prefer this

Use this endpoint when you need a deep forensic profile of a specific deployer wallet — including full contract history and scam flags — rather than just a quick trust score. Prefer this over the quick wallet trust score endpoint when performing due diligence on a new DeFi protocol, evaluating a token before investment, or investigating a suspicious contract interaction.

## Known failure modes

- Invalid or malformed deployer address returns a 400 error
- Unknown or brand-new address with no on-chain history may return empty history and neutral score
- Chain data unavailability may cause partial results or timeout
- Payment failure (x402) results in 402 response before any analysis is performed
- Rate limiting may occur under high request volume

## Output

Returns a forensic profile of the deployer address including: full history of contracts deployed by the wallet, any scam or rug-pull flags associated with the deployer, and a reputation/trust score indicating the deployer's overall risk level.
