Keyless. Members of both Houses, current and historical.\n\n## `take` — clamped to 20, and the response tells you so only by echo\n\n| Request | `items` | `take` echoed | `totalResults` |\n|---|---|---|---|\n| `GET /Members/Search?Name=Smith&take=2` | 2 | 2 | 53 |\n| `GET /Members/Search?Name=Smith&take=100` | **20** | **20** | 53 |\n| `GET /Members/Search?Name=Smith&take=500` | **20** | **20** | 53 |\n| `GET /Members/Search?take=2` (no `Name`) | 2 | 2 | **5260** — `Name` is optional; the unfiltered set is every member ever |\n\nThe `take=100` and `take=500` bodies were byte-identical (22,174 bytes). HTTP 200 in every case. The **only** signal that your page size was cut is `\"take\":20` in the envelope and `links[rel=page.next].href` saying `skip=20&take=20`. Contrast the sibling Bills API on `bills-api.parliament.uk`, which honours `Take=5000`.\n\n## `skip` past the end — 200, empty, and a self-referential next link\n\n`GET /Members/Search?Name=Smith&skip=100000&take=5` → **200**:\n\n```\n{\"items\":[],\"totalResults\":53,\"resultContext\":\"\",\"skip\":100000,\"take\":5,\n \"links\":[{\"rel\":\"self\",\"href\":\"/Members/Search?skip=100000&take=5\",\"method\":\"GET\"},\n          {\"rel\":\"page.next\",\"href\":\"/Members/Search?skip=100000&take=5\",\"method\":\"GET\"},\n          {\"rel\":\"page.previous\",\"href\":\"/Members/Search?skip=99995&take=5\",\"method\":\"GET\"}],\n \"resultType\":\"MemberName\"}\n```\n\n`page.next` is present and equals `self`. A crawler that loops \"while page.next exists\" never terminates; stop when `items` is empty or `skip >= totalResults`.\n\n## Not-found and bad-id shapes\n\n| Request | HTTP | Content-Type | Body |\n|---|---|---|---|\n| `GET /Members/999999999` | **404** | `text/plain; charset=utf-8` | `The resource 999999999 was not found` (36 bytes) |\n| `GET /Members/abc` | **400** | *(none)* | empty, `content-length: 0`, `cache-control: public,max-age=30` |\n| `GET /Members/172` | 200 | `application/json` | `{\"value\":{\"id\":172,\"nameListAs\":\"Abbott, Ms Diane\",…` |\n| `GET /Members/172` + `Accept: application/xml` | 200 | `application/json` | identical — **Accept is ignored** |\n\nNot RFC 7807 problem-details on either failure.
