## 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 kubiaka-now-japan-change-feed-8dbcf7e1 -d '<json body>'
```

Example prompt: What's changed in the Kubiaka invasive beetle situation in Japan since 2024-06-01? I want to see any new damage reports, municipality classification changes, new subsidies, new contact windows, and any deadlines coming up in the next 30 days.

## When to prefer this

Choose this endpoint when you need an incremental update on the Kubiaka invasive beetle situation in Japan since a known date — analogous to a changelog or diff. It is ideal for polling/monitoring workflows where you want only new or changed information rather than the full dataset for a specific municipality. Use the sibling '市町村のカルテ' endpoint instead when you need a comprehensive profile for a specific municipality.

## Known failure modes

- Missing or malformed 'since' date parameter returns an error
- Future dates or dates far in the past may yield empty results or errors
- Payment failure (x402, Base Sepolia USDC) will block the request
- Service may be unavailable if the underlying data source is not updated
- Network timeout if the dataset is large for a wide date range

## How this service works

クビアカのいま 変化の便り: since=YYYY-MM-DD から今日までに変わったものだけ（新たな被害・区分の変化・補助と奨励金の追加と状態の変化・窓口の追加・締切が30日以内のもの）。x402 で $0.01（試験中・Base Sepolia の USDC）

## Output

A filtered list of changes since the specified date, covering: newly recorded Kubiaka pest damage sites, municipality risk-classification changes, newly added or status-changed subsidies and incentive programs, new response contact windows, and any item with a deadline falling within 30 days of today. Only changed or new items are returned, not the full dataset.
