## 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 x402donghang-token-due-diligence-ebb2660a
```

Example prompt: Run a due diligence check on HYPE — I want to know the risk level, liquidity situation, and any red flags or green flags, focusing on security. Reply in English.

## When to prefer this

Choose this endpoint when you need a fast, structured, AI-generated risk snapshot for a specific crypto token, especially when you want a machine-readable verdict (risk score, flags, holder concentration) rather than a lengthy narrative. Particularly useful for agents automating pre-trade screening or building crypto research pipelines. Supports both English and Chinese output. Prefer alternatives if you need real-time price data, order book depth, or official audit reports.

## Known failure modes

- Unknown or very new token symbol with no on-chain data — may return empty flags or inconclusive verdict
- Invalid or malformed contract address — may fail validation or return generic analysis
- Token with extremely low liquidity may produce unreliable liquidity assessments
- Payment not received via x402 — request blocked with 402 Payment Required
- Network timeout or model inference failure — returns error response
