Input schema
| Property | Type | Required | Description |
|---|---|---|---|
| company_number | string | yes | Companies House company number, also called the company registration number (CRN). Accepted shapes are the register's own — 1-8 digits (zero-padded to 8, e.g. 445790 → 00445790), one letter + 7 digits (R0000001), two letters + 6 digits (SC002180, NI000001, OC123456, OE000001), or the registered-society suffix forms (two letters + 5 digits + 1 letter; two letters + 4 digits + 2 letters). Case-insensitive; surrounding whitespace is ignored (which is why maxLength is 10); internal spaces and punctuation are not accepted. Any other value (for example PROBE) is rejected as INVALID_INPUT before payment and before any upstream call. |
| role | string | no | Which appointments to return. Default `director` — the capability's name is its contract. The register encodes the office in officer_role, so the filter is a substring test on it: `director` matches director, corporate-director, nominee-director and corporate-nominee-director; `secretary` matches secretary, corporate-secretary, nominee-secretary and corporate-nominee-secretary; `llp_member` matches llp-member, llp-designated-member and their corporate- forms; `all` returns every appointment the register lists, including managing officers, general partners, judicial factors and the EEIG/SE organ roles. Filtering is applied after the register read, so read page.has_more rather than items.length. |
| include_resigned | boolean | no | Include resigned officers. Default false. |
| limit | integer | no | Maximum officers to return per page (1-100). Default 5. Eckari reads up to three register pages of 100 entries to fill this after the role and resigned filters are applied; if the limit is still unmet, page.has_more is true and page.next_offset says where to resume. |
| offset | integer | no | Zero-based index into the register's own officer list (not into the filtered result). Pass back page.next_offset from the previous response to page. |
