## 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 presign-guard-token-verdict-d403ecdf
```

Example prompt: Can you run a safety check on this Solana token — mint address is 7xKXtg2CW87d97TXJSDpbD5jBkheTqA83TZRuJosgAsU — and tell me if it's safe to buy, what grade it gets, and any red flags like mint authority or honeypot?

## When to prefer this

Use this endpoint when you need a comprehensive, multi-factor token safety verdict covering both Solana and EVM chains in a single call. It combines honeypot detection, mint/freeze authority checks, LP lock status, tax analysis, liquidity, age, and holder concentration into one graded verdict — ideal for pre-trade due diligence, DeFi agent workflows, or automated token screening pipelines. Prefer this over single-factor checkers when you need a holistic SAFE/CAUTION/RISKY/AVOID grade with human-readable reason codes.

## Known failure modes

- Invalid or unrecognized token address returns an error
- Unsupported blockchain network returns unsupported chain error
- Token too new or with no on-chain data may return incomplete analysis
- Rate limiting or payment failure (x402) if USDC payment is not included
- Network timeout if on-chain data sources are slow
- Token with no liquidity pool may return limited verdict data

## How this service works

Is this token safe to buy, or a honeypot or rug pull? Checks a Solana or EVM token before you buy, hold or accept it (mint or freeze authority still active, LP not locked, buy/sell tax, low liquidity, brand-new token, concentrated holders) and answers green/orange/red with a grade (SAFE/CAUTION/RISKY/AVOID), the reasons, a one-line summary and market data

## Output

Returns a structured verdict containing: a color signal (green/orange/red), a letter grade (SAFE/CAUTION/RISKY/AVOID), an array of reason codes flagging specific risks (e.g. MINT_AUTHORITY, HONEYPOT, HIGH_TAX, UNLOCKED_LP, LOW_LIQUIDITY, OLD_AGE, HIGH_CONCENTRATION), a human-readable one-line summary of the risk assessment, and supporting market data such as liquidity amount, token age, holder distribution, and tax rates.
