## How to call it through Zero

```sh
zero fetch --capability silverback-x402-onrender-com-9dab92bf
```

Example prompt: Can you run a full security audit on this token contract 0x1234abcd... on Base chain (chainId 8453) — I want to know if it's a honeypot, what the buy/sell taxes are, and who controls it before I invest.

## When to prefer this

Use this endpoint when you need a comprehensive, multi-factor security assessment of a token contract before trading or investing, especially on Base chain. Ideal for detecting honeypots, verifying tax rates, and checking ownership renouncement in a single call rather than making multiple separate requests.

## Known failure modes

- Invalid or non-existent contract address returns error
- Unsupported chain ID returns chain not supported error
- Token not yet indexed or too new may return incomplete data
- Payment failure (x402) returns 402 Payment Required
- Rate limiting or server overload returns 503
