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. |
| status | string | no | Which charges to return. Default `all`. `outstanding` returns the charges that are still security over the company (everything the register has not marked satisfied or fully-satisfied, including part-satisfied); `satisfied` returns the discharged ones. The register offers no server-side filter, so Eckari applies it after reading up to three register pages of 100 charges — read page.has_more rather than items.length. |
| detail | string | no | How much of each charge to return. Default summary. `full` adds the four members the register populates only for particular filings — acquired_on, resolved_on, assets_ceased_released and more_than_four_persons_entitled — which are null on the great majority of charges. |
| limit | integer | no | Maximum charges to return per page (1-100). Default 3: a charge carries free-text particulars, secured details and the persons entitled, so it is several times the size of an officer or a filing row - the register-wide counts and page.total still describe the whole register. |
| offset | integer | no | Zero-based index into the register's charge list (not into the filtered result). Pass back page.next_offset from the previous response to page. |
