## 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-multi-chain-token-safety-check-9d7fde45
```

Example prompt: Can you rug-scan this token contract 0xAbC123...def on Base and tell me if it's safe to buy?

## When to prefer this

Use this endpoint when you need a quick, structured safety verdict (score + label) for a specific token contract before executing a trade or recommending a token to users. It is particularly well-suited for automated pre-swap checks in trading bots or alert systems across Base, Solana, and Arbitrum, where a binary SAFE/RUG signal with a numeric confidence score is sufficient for decision-making.

## Known failure modes

- Invalid or unsupported chain identifier returns an error
- Malformed or non-existent contract address returns an error or low-confidence result
- Newly deployed contracts with no on-chain history may produce inconclusive results
- Payment failure (insufficient USDC) blocks the request
- Network latency on the target chain may delay analysis

## 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 (0-100) and a categorical verdict such as 'SAFE' or 'RUG', indicating the overall risk level of the scanned token contract on the specified chain.
