## How to call it through Zero

```sh
zero fetch --capability defi-hugen-tokyo-961f17ed
```

Example prompt: Can you run a rug pull risk check on this token — contract address 0xabc123... on Ethereum — and tell me if the liquidity is locked, whether admin keys are renounced, and if there are any hidden mint functions or suspicious ownership concentration?

## When to prefer this

Use this endpoint when you need a comprehensive, multi-factor rug pull risk assessment for a DeFi token — especially when you want to check ownership concentration, liquidity lock status, hidden mint functions, and admin key renouncement in a single call without needing an API key.

## Known failure modes

- Invalid or unrecognized contract address returns error
- Unsupported blockchain network returns unsupported chain error
- Contract not yet indexed or too new may return incomplete data
- Network congestion may slow on-chain data retrieval
- Rate limiting or payment failure returns 402 or rejection
