What you get

What the API gives you

01

One API surface for the UK registry

Query companies, officers, PSCs, filings, and monitoring from a single developer-facing API instead of stitching together raw public endpoints in application code.

02

Built for live product flows

Entylink is positioned for self-serve implementation, predictable pricing, and fast request handling, which matters more than raw access when the registry sits in signup and underwriting paths.

03

Monitoring included in the product story

The value is not only the initial lookup. It is also being able to subscribe to changes and keep downstream systems current without manually owning stream processing.

Implementation

API example
const response = await fetch("https://api.entylink.com/v1/company/08804411", {
  headers: {
    Authorization: `Bearer ${process.env.ENTYLINK_KEY}`,
  },
});

const { data: company } = await response.json();

console.log(company.company_name);
console.log(company.company_status);
Use the company record as the anchor, then expand into officers, PSCs, filings, and monitoring.
Why teams switch

Why teams choose Entylink

01

They need a cleaner developer experience than the official raw interface alone.

02

They want transparent pricing and self-serve onboarding instead of a vendor sales cycle.

03

They need structured registry data to sit inside onboarding, fraud, or credit workflows rather than in a research dashboard.

FAQ

Frequently asked questions

Is Entylink just a proxy for Companies House?

No. The underlying records originate with Companies House, but Entylink packages them into a self-serve, developer-first API with structured access, pricing clarity, and monitoring workflows for production systems.

What fields does the company endpoint return?

The company record includes company name, number, status, type, registered address, SIC codes, incorporation date, and accounts and confirmation statement dates. Use it as the anchor for officers, PSC, filings, and monitoring calls.

Why not use the official API directly?

The official API is the authoritative record and is often enough for basic use. Teams move to a product like Entylink when they want a simpler integration path, clearer commercial packaging, and monitoring without owning the raw stream layer.
