## 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-49edcd12 -d '<json body>'
```

Example prompt: Can you do a full risk assessment on wallet address 0x3f5CE5FBFe3E9af3971dD833D26bA9b5C936f0bE and tell me the trust score, any risk flags, and what risk category it falls into?

## When to prefer this

Use this endpoint when you need a comprehensive risk profile for a wallet — including a numeric trust score, specific risk flags, and a categorical risk classification — before interacting with or sending funds to that address. Prefer this over the quick trust score endpoint when you need the full breakdown of flags and classification, not just a single score.

## Known failure modes

- Invalid or malformed wallet address returns a 400 error
- Unsupported blockchain network returns an error indicating network not supported
- Unknown or very new wallet with no on-chain history may return a low-confidence score
- Payment failure via x402 protocol returns 402 Payment Required
- Timeout or service unavailability returns 503

## Output

Returns a trust score (numeric), a list of risk flags (e.g. mixer usage, sanctioned counterparty, high-risk activity patterns), and a risk classification label (e.g. low/medium/high risk) for the queried wallet address.
