No key, no User-Agent requirement observed. Responses are **JSON:API** (`Content-Type: application/vnd.api+json`; sending `Accept: application/json` gets the same body relabelled `application/json`). Note for curl: the `[`/`]` in the query string trip curl's URL globbing (`curl: (3) bad range in URL`) — use `-g`.\n\n## Envelope\n```\n{\"meta\":{\"goldenCopy\":{\"publishDate\":\"2026-09-29T16:00:00Z\"},\n         \"pagination\":{\"currentPage\":1,\"perPage\":15,\"from\":1,\"to\":1,\"total\":1,\"lastPage\":1}},\n \"links\":{\"first\":\"…\",\"last\":\"…\"},\n \"data\":[{\"type\":\"lei-records\",\"id\":\"5493001KJTIIGC8Y1R12\",\"attributes\":{\"lei\":…,\"entity\":{…},\"registration\":{…},\"bic\":null,\"mic\":null,\"ocid\":\"us_de/4348344\",\"qcc\":null,\"gem\":…,\"spglobal\":…,\"conformityFlag\":\"CONFORMING\"},\"relationships\":{\"managing-lou\":…,\"lei-issuer\":…,\"field-modifications\":…,\"direct-parent\":…,\"ultimate-parent\":…},\"links\":{\"self\":\"…\"}}]}\n```\n`meta.goldenCopy.publishDate` is the dataset vintage (the daily Golden Copy) — the freshness stamp to record. Default `perPage` is **15**. `total` on an unfiltered list was **3 446 215** (`lastPage: 17232` at size 200). `ocid` is an OpenCorporates id (`us_de/4348344`); `bic`/`mic`/`qcc` are `null` when absent, not omitted.\n\n## Filters and lookups\n- `?filter[lei]=5493001KJTIIGC8Y1R12` → 200, 1 record. `?filter[lei]=5493001kjtiigc8y1r12` (lower-case) → 200, **same record** — LEI matching is case-insensitive; the returned `id` is upper-case.\n- `?filter[lei]=NOTALEI` → **200** with `data: []`, `pagination.total: 0`, `from`/`to`: `null`. Garbage is an empty result, not an error.\n- `?filter[nonsense]=x` → 400 `{\"errors\":[{\"title\":\"Filter should contain only allowed values.\",\"source\":{\"parameter\":\"filter\"}}]}` — note: no `status` member on this error, unlike the pagination errors below.\n- `GET /lei-records/5493001KJTIIGC8Y1R12` (and lower-case) → 200, `data` is an object, `meta` has only `goldenCopy` (no pagination).\n- `GET /lei-records/5493001KJTIIGC8Y1R99` (unknown) and `/lei-records/NOTALEI` → **404 `text/html`** — a 1 552-byte HTML \"Not Found\" page, **not** a JSON:API `errors` document. A client that parses JSON on every response will fail here.\n- `GET /fuzzycompletions?field=entity.legalName&q=Apple` → 200, `data` (10 items) with no `meta`/`links`.\n\n## Pagination — hard limits, with the fix in the error text\n- `page[size]=201` or `500` → **400** `{\"errors\":[{\"status\":\"400\",\"title\":\"Invalid Query Parameter\",\"detail\":\"The page.size must be between 1 and 200.\",\"source\":{\"parameter\":\"page.size\"}}]}` — a refusal, not a silent clamp. `page[size]=200` → 200 with 200 records (486 408 B).\n- `page[size]=1&page[number]=100000` → **400** `…\"detail\":\"Deep page-based pagination is not supported beyond 10000 results (the product of page[number] * page[size] must not exceed 10000).
