## 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 01mind-legal-research-knowledge-api-37f21cb8 -d '<json body>'
```

Example prompt: Can you look up the current legal standard for negligence under US tort law, with citations to key cases and any relevant statutory guidance?

## When to prefer this

Choose this endpoint when you need grounded, cited legal research referencing real statutes, case names, and regulatory documents rather than a generic AI-generated legal summary. Prefer this over general LLM queries when citations and authoritative sourcing matter, or when building a legal research workflow that requires traceable references.

## Known failure modes

- Question too vague or ambiguous to retrieve precise citations
- Jurisdiction not specified, resulting in general rather than jurisdiction-specific guidance
- Very recent legislation or rulings may not be indexed yet
- Highly niche or obscure area of law may return limited results
- Malformed POST body or missing required fields returns an error

## How this service works

Ask a real legal-research question, answered live and grounded in real, named legislation/case law/regulator guidance. Informational reference material only, not legal advice -- see the disclaimer on every response.

## Output

A detailed, grounded response citing specific named legislation, case law, and/or regulatory guidance relevant to the question asked. Each response includes a disclaimer that the information is for informational/reference purposes only and does not constitute legal advice.
