## 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 tokenguard-erc-20-token-safety-brief-1cf0c8d7 -d '<json body>'
```

Example prompt: Can you run a safety check on the ERC-20 token at address 0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed on Base — I want to know the risk score, any dangerous functions like blacklisting, and whether there's enough liquidity to exit safely.

## When to prefer this

Use this endpoint when you need a fast, structured risk brief on a specific ERC-20 token before a trade, investment, or DeFi interaction — especially when you want a single verdict plus actionable flags like blacklist functions or thin liquidity. Prefer it over generic blockchain explorers when you need a machine-readable risk score and plain-language flags rather than raw contract data.

## Known failure modes

- Invalid or non-existent contract address returns error or empty analysis
- Unsupported chain returns error (default is Base)
- Token with no on-chain data may return incomplete risk assessment
- CoinGecko ID mismatch results in missing developer activity data
- Rate limiting or payment failure (x402) blocks the request

## How this service works

One-call token due diligence: structural rug/safety scan, live liquidity and market depth, optional dev activity, resolved into a single ok/caution/avoid verdict with the flags that drove it.

## Output

Returns a JSON object with: a verdict string (e.g. 'avoid'), a risk_level label (e.g. 'high'), a numeric risk_score (0-100), a list of top_flags describing specific dangers (e.g. dangerous contract functions, thin liquidity warnings), a liquidity_usd figure, and a thin_liquidity boolean.
