## 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 japan-regulatory-events-headlines-feed-d8deecdf
```

Example prompt: Pull the latest 20 Japan regulatory headlines since 2025-01-01 from all sources — I need both the original Japanese titles and the machine-translated English versions.

## When to prefer this

Use this endpoint when you only need headline-level awareness of Japan regulatory events across all 11 sources and do not require summaries or full event details. It is the lowest-cost entry point ($0.002/call) for monitoring Japan regulatory activity. Prefer the /v1/reg/events endpoint when full summaries or structured event data are needed.

## Known failure modes

- Invalid 'since' date format returns 400 bad request
- Unsupported 'category' value returns empty result set or 400
- Exceeding rate limits returns 429 Too Many Requests
- Payment not processed (x402) returns 402 Payment Required
- No new events in requested window returns empty array

## How this service works

Cheapest tier: headlines only (original + machine-translated title) across all 11 Japan regulatory sources, no summary. Upsell entry point to /v1/reg/events. Factual; not legal advice.

## Output

A list of headline entries from up to 11 Japan regulatory sources, each containing the original-language title and a machine-translated English title, optionally filtered by date (since) and category, with no summary text included.
