Endpoint
GEThttps://api.agentfeeds.jp/v1/reg/events/taxWhen to prefer
Use this endpoint when you need up-to-date, human-reviewed English summaries of Japan tax authority actions affecting crypto assets — particularly NTA guidance, CARF implementation events, or annual tax reform notices. Prefer this over generic news APIs when you need structured, factual regulatory data scoped specifically to Japan tax and crypto, not general financial news.
Side effects

- Invalid 'since' date format causes a 400 bad request
- Limit parameter out of range may return an error or be clamped
- Service temporarily unavailable returns 5xx error
- Payment failure (x402) prevents access to the feed
