Companies House Streaming API

The Companies House Streaming API delivers real-time changes to Companies House data via long-running HTTP connections. It streams updates across nine data categories including company information, filing history, insolvency, charges, officers, persons with significant control, disqualified officers, exemptions, and PSC statements. Each account is limited to two concurrent streaming connections and requires an API key for authentication.
