What you get

What the API gives you

01

Structured access to the registry surfaces that matter

Entylink groups the core UK registry workflows around companies, officers, PSCs, filings, and monitoring so teams can model entities coherently in product code.

02

Designed for downstream workflows

Production teams usually need more than a single company lookup. They need a stable way to move from entity search into ownership, appointments, filing history, and ongoing alerts.

03

Commercially legible from day one

Entylink pricing is public and fixed by plan. No vendor quote, no annual commitment, no separate onboarding call — just a free tier and transparent paid tiers when volume grows.

Registry flows usually start with the company number and branch into filings, officers, PSCs, and monitoring from there.
Why teams switch

Why teams choose Entylink

01

They want one coherent API surface instead of separate ad hoc integrations.

02

They need a provider that is legible to engineering and procurement at the same time.

03

They want registry data as infrastructure, not a lookup dashboard.

FAQ

Frequently asked questions

What makes this a registry API rather than just a company lookup API?

The page targets teams that need the wider registry workflow: entity details, officers, persons with significant control, filing history, and change monitoring.

Is this UK-only?

Yes. Entylink's positioning is specifically around UK company registry and Companies House data, which keeps the product sharper for UK-focused product and compliance teams.

Do I need to combine multiple endpoints for a full registry review?

Yes — a complete entity review typically chains company, officers, PSC, and filings in sequence. All four share the same API key and return consistent JSON response shapes.
