This server connects your AI client to the EDINET API (Version 2) operated by Japan's Financial Services Agency. EDINET is the official electronic disclosure system where listed companies and funds file their securities reports.

Key features:

  • List all documents filed on a given date, with each filer's name, securities code, corporate number, document type, and covered period.
  • Narrow the list by filer-name keyword, document type code (e.g. 120 = annual securities report), or securities code.
  • Use the returned docID to look the document up on the EDINET viewer (disclosure2.edinet-fsa.go.jp).

Annual securities reports (ζœ‰δΎ‘θ¨ΌεˆΈε ±ε‘Šζ›Έ) contain segment financials, risk factors, shareholder composition, and officer compensation - the raw material for competitor and business-partner analysis. Because filings include the corporate number, results join cleanly with gBizINFO and the Corporate Number System.

Using the API requires a free API key issued through the EDINET API registration. Set it as EDINET_API_KEY in your Arlet environment variables.
