不動産競売 構造化データハブ — Japan real-estate auctions
Connects Claude to Japan's official court-run real estate auction registry (BIT) with five tools for searching, filtering, and retrieving structured auction data. You can search across ~1,480 active listings by prefecture, court, property type, price range, or Japanese keyword, pull full case details including photos and bid periods, list upcoming sales within a rolling window, and look up court codes or professional practitioner directories for post-acquisition legal work. Data refreshes twice daily and is published under CC BY 4.0. Useful if you're building tooling around Japanese real estate auctions, need programmatic access to court sale data, or want LLM-friendly structured alternatives to the session-bound BIT interface.
