Tools

Functions exposed to the LLM to take actions

NameDescription
validate_corporate_numberA

Validate a 13-digit Japanese corporate number (法人番号) offline: format + official NTA check-digit formula. Does NOT confirm the company exists in the registry (use lookup_corporate_number for that).

lookup_corporate_numberA

Enrich a 13-digit corporate number with registry data (name, address, kind, dates). Uses the NTA 法人番号 Web-API when NTA_APP_ID is set; otherwise falls back to bundled SYNTHETIC sample data (clearly tagged).

search_corporations_by_nameA

Search corporations by (partial) name. Live NTA Web-API when NTA_APP_ID is set; otherwise searches the bundled SYNTHETIC sample set.

lookup_bankA

Look up a Japanese bank by its 4-digit zengin bank code (統一金融機関コード). Returns name / kana / hiragana / romaji.

search_banksA

Search Japanese banks by name fragment (kanji / kana / hiragana / romaji all matched). Returns zengin codes + names.

lookup_branchA

Look up a bank branch by 4-digit bank code + 3-digit branch code (支店コード). Branch data is lazily fetched from the public zengin-code dataset and cached locally.

japan_holidaysB

List Japanese national holidays for a year (official Cabinet Office syukujitsu.csv, bundled).

is_japan_holidayA

Check whether a date (YYYY-MM-DD) is a Japanese national holiday.
