## 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 token-safety-api-klymax402-com-c5a6f952
```

Example prompt: Can you check whether the token at contract address 0xdAC17F958D2ee523a2206206994597C13D831ec7 on Ethereum is safe to interact with — tell me its risk score, whether it's a honeypot, and what the buy/sell taxes are?

## When to prefer this

Use this endpoint when you need to quickly assess whether a specific ERC-20 token contract is safe to trade or interact with on Ethereum or Base — especially when checking for honeypot traps, high taxes, blacklisting, or mint risks before a DeFi transaction. Prefer this over general blockchain explorers when you need a structured risk score and safety flag set in a single call.

## Known failure modes

- Unknown or unverified contract address returns found:false with no safety data
- Unsupported chain value returns an error or empty response
- Malformed address (non-0x format) likely returns a validation error
- Rate limiting or payment failure may return 402 or 429 status codes
- Very new tokens may lack holder or tax data

## How this service works

Check token contract safety and risk score

## Output

Returns a risk_level (e.g. 'caution', 'safe', 'high risk'), numeric risk_score (0-100), boolean safety flags (is_proxy, is_honeypot, is_mintable, is_anti_whale, is_blacklisted, is_open_source, cannot_sell_all, can_take_back_ownership), buy and sell tax rates, holder count, LP holder count, token name/symbol, total supply, owner address, creator address, chain ID, and a cache expiry timestamp.
