    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    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.

    Description, as the server wrote it
    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.

    Description, as the server wrote it
    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.

    Description, as the server wrote it
    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.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
