## 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-711e0a30 -d '<json body>'
```

Example prompt: Can you find all the related wallets and interaction clusters for the address 0x1234567890123456789012345678901234567890 — I want to know what wallets it interacts with, where it was funded from, and what contracts they share?

## When to prefer this

Use this endpoint when you need to discover wallet clusters, trace funding sources, or map on-chain social graphs around a specific address. Particularly useful for fraud detection, AML screening, due diligence on counterparties, or understanding the network of wallets surrounding a DeFi participant. Prefer this over a basic trust score endpoint when you need the full relational graph rather than a single risk score.

## Known failure modes

- Invalid Ethereum address format returns an error
- Address with no on-chain transactions returns empty related_wallets and common_contracts arrays with a summary indicating no transactions found
- Network timeout or upstream RPC failure may return a 500 error
- Malformed JSON request body returns a 400 error

## Output

Returns a cluster analysis object containing the queried address, a natural language summary, the funding source address (if found), a list of related wallet addresses, a list of common contracts shared among clustered wallets, and the response time in milliseconds. Returns empty arrays when no transactions or relationships are found.
