## 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-a8d726ba
```

Example prompt: Can you run a rug scan on this Base network contract 0x1234567890abcdef1234567890abcdef12345678 and tell me if it's safe to buy?

## When to prefer this

Use this endpoint when you need a quick, paid, per-call rug pull safety assessment for a specific token or contract address on supported chains including Base, Solana, and Arbitrum. Prefer this over free alternatives when you need a structured score and verdict with multi-chain support in a single API call.

## Known failure modes

- Unsupported chain name returns an error or empty result
- Invalid or malformed contract address returns an error
- Contract not yet indexed on the supported chain returns no data
- Rate limiting or payment failure returns 402 or 429
- Newly deployed contracts may have insufficient on-chain data for scoring

## 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 risk score (e.g. 85 out of 100) and a categorical verdict such as SAFE or UNSAFE, indicating the likelihood that the contract is a rug pull or scam.
