## 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 law-mcp-toulaw-workers-dev-101f4331
```

Example prompt: Search for laws and regulations about 'digital assets' across all jurisdictions — JP, US, UK, and EU — and give me up to 15 results per jurisdiction.

## When to prefer this

Use this endpoint when you need to search legal texts and legislation across multiple major jurisdictions (Japan, US, UK, EU) simultaneously with a single keyword query. It is ideal for cross-jurisdictional regulatory research, compliance checks, or identifying which countries have laws touching on a specific topic. Prefer this over generic web search when you specifically need structured legislative database results rather than news articles or legal commentary.

## Known failure modes

- Missing required 'q' query parameter returns a validation error
- Invalid 'country' enum value (not one of all/jp/us/uk/eu) causes a bad request error
- Exceeding limit of 20 results per jurisdiction is clamped or returns an error
- Payment failure (x402) prevents access to results
- No matching legislation found returns an empty result set
- Timeout on upstream legislation database may return partial or no results
