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）
Output
A filtered JSON response listing only the entities that changed between the specified 'since' date and today: new damage locations, municipality classification changes, newly added or status-changed subsidies and incentives, new contact/reporting windows, and any deadlines falling within 30 days. If 'since' is omitted, defaults to 7 days ago.
Example use cases
Weekly Kubiaka situation briefing
“Give me a summary of everything that changed in Japan's Kubiaka beetle situation over the past 7 days — new damage areas, any municipality reclassifications, and subsidy updates.”
Monitoring new subsidy deadlines
“Check Kubiaka Now for any new subsidies or incentive programs added since 2024-04-01, especially ones with deadlines coming up in the next 30 days.”
Tracking spread into new municipalities
“Have any new municipalities been added to the Kubiaka damage or risk classification since May 15th, 2024? Pull the changes feed from that date.”
Technical details
Endpoint
GEThttps://kubiaka-now.com/x402/v1/changes?utm_source=zero.xyzWhen to prefer
Use this endpoint when you want only the delta — what changed since a specific date — rather than a full profile of a single municipality. It is the right choice for monitoring workflows, weekly briefings, alert systems, or any scenario where you want to avoid re-processing unchanged data. For a comprehensive profile of one specific municipality including all current details, prefer the municipality card sibling endpoint instead.
Side effects
- Invalid date format for 'since' parameter — must be YYYY-MM-DD
- No changes in the requested period — returns empty result set
- Future date passed as 'since' — may return empty or error
- Payment failure via x402 — request blocked if USDC payment is not fulfilled
- Network timeout if upstream data source is unavailable
