## 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 wallet-on-chain-risk-trust-scorer-5473ed1b
```

Example prompt: Before I send funds, can you check the trust and risk level for wallet 0x1234abcd...5678 to make sure it doesn't have any suspicious on-chain activity?

## When to prefer this

Use this endpoint when you need a quick, per-wallet trust assessment before initiating a transaction — especially when the counterparty wallet is unknown or comes from an untrusted source. Prefer this over generic block explorers when you need a structured risk score rather than raw transaction data. Best suited for DeFi agents, payment automation, and any workflow where screening a wallet address before sending value is critical.

## Known failure modes

- Invalid or malformed wallet address returns an error or null result
- Unsupported chain or address format not recognized
- Rate limiting if too many requests are made in quick succession
- Empty on-chain history may result in an inconclusive or default risk score
- Network timeout if the underlying on-chain data provider is slow

## How this service works

Check any wallet on-chain activity and risk level before transacting

## Output

Returns a risk or trust score for the queried wallet address, along with a breakdown of on-chain activity indicators such as transaction history signals, suspicious behavior flags, and an overall risk classification (e.g. low/medium/high risk).
