## 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 rules-gen-mcp-3f25df5d -d '<json body>'
```

Example prompt: Can you generate a set of validation rules from this data: 'users must be over 18, email must be verified, and account balance must be non-negative'?

## When to prefer this

Choose this endpoint when you need to automatically generate structured rules or policies from natural language or structured input data, especially in agentic pipelines that require rule synthesis without manual authoring.

## Known failure modes

- Empty or malformed 'data' field returns an error or empty rule set
- Ambiguous input may produce generic or unhelpful rules
- Payment failure (402) if x402 payment header is missing or insufficient
- Timeout if input data is very large or complex
- Rate limiting if called too frequently
