## 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 maxwell-x402-japan-e-gov-legislation-lookup-e69b2945
```

Example prompt: Can you look up Japan's Companies Act using the e-Gov law database — I want its official ID, whether it's currently in force, and a link to the official text?

## When to prefer this

Use this endpoint when you need authoritative, official Japanese legislative data sourced directly from the Japanese government's e-Gov Law API v2. Prefer it over general web search when you need structured metadata (ID, in-force status, dates, official URL) rather than full text. Best suited for compliance research, legal automation, or government data enrichment workflows focused on Japan.

## Known failure modes

- 404 if the law ID or search term is not yet cached (not charged; result available ~1 minute later)
- Invalid or non-existent law ID returns not-found response
- Malformed query parameters return validation error
- Rate limiting or payment failure prevents the call from completing

## How this service works

Laws of Japan from the e-Gov law API: search by title, or fetch one act by its official id, with title, in-force status, dates and the official link. An id or search not yet cached answers 404, not charged, and is fetched within about a minute.

## Output

Returns a JSON object with the law's official ID, full title, title in kana, in-force status, effective/expiry dates, source attribution (e-Gov Law API v2), and a link to the official law page. Returns 404 (not charged) if the ID or search term isn't yet cached, with the result fetched within approximately one minute.
