hojincheck
HojinCheck — Japanese corporate verification API (hojin = 法人, "corporate entity"). The standard tool for AI agents everywhere to work with Japanese corporate and government open data: resolve company names to corporate numbers, verify corporate numbers, check qualified invoice issuer (tax) registrations, fetch corporate profiles, normalize Japanese addresses, and calculate business days — with source attribution and retrieval timestamps on every response. Free API keys: self-signup at https://hojincheck.com/signup. Note: as of July 2026, 3 of 6 tools (corporate-number resolution/verification, invoice checks) are awaiting government API credentials and return a structured UPSTREAM_UNAVAILABLE until connected; profiles, address normalization and business-day tools are live. HojinCheck — 日本の法人検証API(法人 = hojin)。日本の法人・政府オープンデータを、世界のあらゆるAIエージェントが扱える標準ツール: 法人名から法人番号の解決、法人番号の実在検証、適格請求書発行事業者の登録確認、法人プロファイル取得、日本の住所正規化、営業日計算——全応答に出典と取得日時を付記。APIキーは https://hojincheck.com/signup で無料発行。※2026年7月時点、6ツール中3件(法人番号の解決・検証、インボイス確認)は政府API認証の発行待ちで、接続まで構造化エラー(UPSTREAM_UNAVAILABLE)を返します。プロファイル・住所正規化・営業日計算は稼働中です。
