UK Company Enrichment
2 credits / callA UK company name or domain → a verified profile in one call.
Companies House facts, an AI summary of what the business actually does, filing signals and an honest accuracy score — on every result.
Raw registry APIs hand you codes and dates and leave the real question — what does this business actually do? — unanswered. This endpoint answers it: one call takes a company name or a bare domain and returns the registered facts from Companies House, an AI-written summary of what the business does read from its own website, filing signals worth acting on, and an accuracy score that shows exactly how the answer was earned. It's the difference between storing data about a company and actually knowing who you're dealing with — and it's the foundation every other API on this platform is built on.
what you’d build with it
CRM autofill
A new lead types their email — you show their full company profile before your rep even opens the record. One call on the signup webhook.
Onboarding & KYB-lite
Verify who a business actually is (registered name, status, age, what they do) before you extend credit, access or trust.
Directories & marketplaces
Every listing self-populates with verified facts and an AI summary — no manual data entry, no stale profiles.
Sales research at machine speed
The 20 minutes a rep spends googling a prospect becomes a 2-second call — with a filing-signals section researchers usually miss.
Data hygiene
Nightly re-enrichment keeps company records honest: status changes, new SIC codes and dissolved companies surface themselves.

Why developers pick it
Not just registry data
Companies House gives you codes and dates. We add an AI summary of what the business actually does — the part raw registry APIs can't.
An honest accuracy score
Every result carries a grounded 0–100 confidence score that shows its work, so you know exactly how much to trust it.
Built for the UK
Native Companies House depth — SIC codes, filing signals, incorporation dates — not a global tool bolted onto the UK.
Flat, transparent pricing
Two credits per call on this endpoint on every plan, free included (only the premium endpoints count double on the free tier). No notice periods. Cancel anytime.
