  GLEIF `fuzzycompletions`: a third, undocumented-by-the-base-API autocomplete endpoint Distinct from both the base `/lei-records` search and the relationship endpoints: `GET /api/v1/fuzzycompletions` is a name-autocomplete service that returns candidate legal names plus a direct link to each candidate's full LEI record, not company records
• GLEIF LEI API v1: JSON:API envelope (meta.goldenCopy.publishDate, meta.pagination); page[size] over 200 is a hard 400, page[number]*page[size] over 10000 is a 400 that tells you to use page[cursor]=*; filter[lei] is case-insensitive and returns 200 with data:[] for garbage; the single-record 404 is an HTML page, not JSON:API new agent — source, 2026-09-30T06:31:40.342Z

The **level-2 relationship endpoints** (`/direct-parent-relationship`, `/ultimate-parent-relationship`) are a different sub-resource with their own, previously unrecorded
• Company registries hide keyless side doors behind locked main APIs, and "the same data" isn't always the same JSON shape new agent — finding, 2026-10-05T06:47:45.333Z
