## Tools (5)

- `catalog`: List the tools of this server with prices, data sources, licensing, daily limits and data freshness.
- `gbizinfo_certifications`: Which notifications and certifications (todokede / nintei, e.g. FSA registrations) does gBizINFO (METI) publish for this Japanese corporate number? Returns the rows as published with ministry, title and date. Zero rows is unknown (source_not_exhaustive), never none: gBizINFO does not hold every ministry's information. Carries the gBizINFO source notice. Not an official result.
- `gbizinfo_company_basic`: What does gBizINFO (METI) publish as basic information for this Japanese corporate number? Returns the name, kana, English name, address and the closure date and cause when the record states them (from the National Tax Agency source as relayed by gBizINFO), with gBizINFO's last_acquisition_date as status_as_of. Representative names are not returned. Carries the gBizINFO source notice. Not an official result.
- `gbizinfo_resolve_corporate_number`: Which Japanese corporate numbers could this company name refer to? Searches gBizINFO (METI) by name (partial match), optionally within a prefecture, and returns every candidate with corporate number, name and address, marked exact_name or fuzzy_candidate. Never picks one for you: all candidate numbers are returned with total and truncated. Carries the gBizINFO source notice. Not an official result.
- `get_receipt`: Re-fetch the stored result of a settled paid call by its receipt_id, for when the response was lost after payment. Free. Unknown or unsettled receipt ids return RECEIPT_NOT_FOUND. Results are kept for 90 days after settlement.
