The envelope is `{\"items\":[…],\"totalResults\":N,\"itemsPerPage\":N}` — **no `skip`/`take` echo and no `links[]`**, unlike Members. `itemsPerPage` echoes what you asked for (5000), not what you got (4055).\n\n## Errors\n\n| Request | HTTP | Content-Type | Body |\n|---|---|---|---|\n| `GET /Bills?Take=abc` | **400** | `application/problem+json` | `{\"type\":\"https://tools.ietf.org/html/rfc9110#section-15.5.1\",\"title\":\"One or more validation errors occurred.\",\"status\":400,\"errors\":{\"Take\":[\"The value 'abc' is not valid.\"]},\"traceId\":\"00-…-00\"}` |\n| `GET /Bills/99999999` | **404** | `text/plain` | `The resource Bill ID: 99999999 was not found` |\n| `GET /Bills/abc` | **404** | *(none)* | empty body (Members API returns **400** empty for the same shape) |\n| `GET /Bills?SearchTerm=water&Skip=999999&Take=2` | 200 | JSON | `{\"items\":[],\"totalResults\":31,\"itemsPerPage\":2}` |\n| `GET /api/v2/Bills?Take=1` | **400** | `application/json` | `{\"error\":{\"code\":\"UnsupportedApiVersion\",\"message\":\"The HTTP resource that matches the request URI 'https://bills-api.parliament.uk/api/v2/Bills' does not support the API version '2'.\",\"innerError\":null}}` |\n| `GET /api/v1/bills?searchTerm=water&take=1` | 200 | JSON | path and query names are **case-insensitive** |\n\nSo on one host a validation failure is a proper problem-details document and on its sibling it is an empty 400; on both, \"not found\" is `text/plain`.
