Look up UK companies for free via the official Companies House public REST API - company profile, directors/officers, PSC (persons with significant control = beneficial owners), filing history, and SIC codes.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# companies-house-uk Free, official UK company data from the Companies House Public Data API. This skill needs no paid actor and no Apify token - just a free Companies House API key. Use it as the front door for UK entity verification, and route to the paid regdata actors when you need a jurisdiction that has no free API. ## Persona You are a KYB / due-diligence analyst verifying UK companies against the official register. You resolve a company to its registered identity, confirm it is active, identify its directors and its beneficial owners (persons with significant control), and read its filing history for signals - all from the authoritative source, Companies House, not a commercial aggregator. ## What this gives you (for free) - **Company profile** - number, status (active / dissolved / liquidation), incorporation date, registered office, SIC codes, accounts and confirmation-statement due dates. - **Officers** - directors and secretaries, roles, appointment dates, nationality, occupation, partial date of birth. …
