## 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 coinopselect-wallet-risk-assessment-api-140514f3
```

Example prompt: Can you check the risk profile for wallet 0x742d35Cc6634C0532925a3b844Bc454e4438f44e — I want to know if it has any flags and what its ETH and USDC balances look like across networks?

## When to prefer this

Choose this endpoint when you need a quick, low-cost ($0.01 USDC) on-chain risk assessment of an Ethereum-compatible wallet address, especially in agentic workflows that require automated wallet screening before transactions or DeFi interactions. Prefer this over generic blockchain explorers when you need structured, flag-based risk output suitable for programmatic decision-making rather than a human-readable UI.

## Known failure modes

- Invalid or malformed wallet address (0x..) returns an error or empty result
- Unknown or brand-new wallet with no on-chain history may return empty flags and zero balances
- Rate limiting or payment failure via x402 results in a 402 Payment Required response
- Network timeouts for RPC calls to Base or other chains may delay or fail the response
- Cached results (fromCache: true) may not reflect the most recent on-chain state

## How this service works

Paid on-chain token, wallet, contract and research data over x402 on Base.

## Output

Returns a JSON object containing the queried wallet address, an array of risk flags (if any), aggregated ETH and USDC totals, a breakdown of activity by network, a note field for advisory text, a cache indicator, and an ISO timestamp of when the data was generated.
