      What this check looks for
    Description, as the server wrote it
    What has this Japanese company or other filer submitted to EDINET in the last 365 days? From this service's day-by-day index of the EDINET document list: document ID, document type (EDINET code and English label, our translation), submission time, period, filer, issuer, tender offer subject and subsidiary codes, parent document, withdrawal, disclosure and correction status, and the EDINET link. Withdrawn filings carry no content. Facts only.

    Annotations the server declares

    • readOnlyHint: true
    • openWorldHint: true
  • edinet_filing_relationsHow is this EDINET filing related to other filings, as EDINET's document list states explicitly?No findings

    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
    How is this EDINET filing related to other filings, as EDINET's document list states explicitly? One hop each: parent document (parentDocID: amendment, change report base, withdrawal), child documents, filer, large shareholding issuer, tender offer subject and listed subsidiaries, plus FSA correction and non-disclosure records. Each relation names its basis field. Targets not in the index are returned as unresolved with reason candidates, never guessed.

    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 large shareholding and tender offer filings name this Japanese issuer? Large shareholding reports, change reports and amendments (EDINET issuerEdinetCode) and tender offer filings (subjectEdinetCode), newest first, from this service's EDINET index. Filer names are given only for organisations; names that appear to be individuals are withheld. A list of filings ordered by time only: no holding ratios and no interpretation of anyone's intentions.

    Why it is in this group

    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.

    Annotations the server declares

    • readOnlyHint: true

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.
