Eckari

Return the current legal status of a UK company from the Companies House register — active, dissolved, liquidation, administration, receivership, voluntary-arrangement and others — with status detail, cessation date, a derived is_active (true for the live-on-the-register statuses active, open and registered) and a derived is_striking_off for an active company with a proposal to strike off. One call, one authoritative register answer. Use when: Is this UK company still active?

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."
