## 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 basebuilder-rug-owner-check-35616fb2 -d '<json body>'
```

Example prompt: Can you run a rug owner check on this token contract 0x1234abcd...5678 — I want to know if the deployer wallet has any rug-pull history before I buy in.

## When to prefer this

Use this endpoint when you need a quick, paid rug-pull owner risk check for a specific token or contract address, especially before making a DeFi investment decision. Prefer this over manual on-chain lookups when you need aggregated risk signals about the deployer wallet's historical behavior.

## Known failure modes

- Invalid or malformed contract address returns 400 error
- Unknown or unindexed contract returns no data found
- Network not supported returns error
- Payment not provided or insufficient returns 402 Payment Required
- Rate limiting or server error returns 500
