## 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 onchaininja-rug-scanner-e4e85cac
```

Example prompt: Can you rug-scan the token at address 0xabc123...def on Base and tell me if it's safe — what's its safety score and verdict?

## When to prefer this

Use this endpoint when you need a quick, on-demand rug pull safety check for a specific token contract address on a supported chain (Base, Solana, Arbitrum, etc.). Prefer this over generic on-chain data providers when you want a pre-computed risk score and a clear safe/unsafe verdict rather than raw contract data.

## Known failure modes

- Invalid or unsupported chain identifier returns an error
- Malformed or non-existent contract address returns an error or null result
- Unrecognized address format may result in a failed lookup
- Payment failure (insufficient USDC) prevents the call from completing
- Chain congestion or RPC issues may cause timeout or stale data

## How this service works

Alpha signals, whale tracking, rug scanning, and MEV protection across Base, Solana, Arbitrum, and more.

## Output

Returns a JSON object with a numeric safety score (e.g. 85 out of 100) and a plain-language verdict such as 'SAFE' or 'UNSAFE', indicating whether the scanned token contract is likely a rug pull or legitimate project.
