## 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 agentfeeds-jp-japan-regulatory-events-history-40ad56a7
```

Example prompt: Pull all reviewed Japan regulatory events from January 1, 2025 to March 31, 2025, category 'guideline', up to 200 results starting at offset 0.

## When to prefer this

Use this endpoint when you need bulk historical retrieval of Japan regulatory events over a defined date range, especially when you want to paginate through many records or filter by a specific regulatory category. Prefer this over the daily digest endpoint when you need multi-day or multi-month historical coverage rather than just yesterday's events.

## Known failure modes

- Missing required 'from' date parameter returns 400 error
- Invalid ISO date format returns 400 error
- Invalid category enum value returns 400 error
- Limit outside 1-200 range returns 400 error
- Date range with no matching events returns empty results array
- Payment failure or insufficient USDC balance returns 402 error
- Server-side timeout for very large date ranges may return 503

## How this service works

Paginated date-range query over reviewed past Japan regulatory events (all sources, optional category filter). For bulk historical retrieval rather than polling. English, human-reviewed. Factual reporting only; not legal advice.

## Output

A paginated list of human-reviewed Japan regulatory events within the requested date range, each with category (bill, pubcomment, guideline, enforcement, or other), source, date, and English-language factual description. Supports offset/limit pagination for bulk historical retrieval.
