## 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 rugcheck-40626fe6
```

Example prompt: Can you scan the Base token at 0x4200000000000000000000000000000000000042 and tell me if it's safe to buy — give me the safety score, risk level, and any red flags like honeypot signals or low liquidity?

## When to prefer this

Choose this endpoint when you need a fast, low-cost ($0.02 USDC) automated safety scan for a Base network token before trading or listing. Ideal for agents performing pre-trade due diligence, filtering token lists, or flagging risky assets in a DeFi portfolio. Best for Base chain specifically — not applicable to tokens on Ethereum mainnet, Solana, or other chains.

## Known failure modes

- Invalid or non-Base contract address returns an error
- Token not indexed on DexScreener returns incomplete data
- Very new tokens with no pair data may lack market metrics
- RPC timeout for onchain checks may delay or fail the response
- Malformed address (not 0x + 40 hex) rejected at input validation

## How this service works

Token safety scanner for Base: 0-100 safety score, risk band, and red flags (liquidity, honeypot signals, upgradeable proxy, pair age, 24h flow) for any Base token contract.

## Output

A JSON object containing: a numeric safety score (0-100, higher is safer), a risk band string (low/medium/high/extreme), the scanned contract address, and a set of red flags covering liquidity depth, honeypot sell-block signals, upgradeable proxy detection, pair age, and 24-hour buy/sell flow metrics.
