Company Data API: search and enrich business data

A company data API is an interface that returns structured information about a business, on request, in JSON. Instead of looking a business up by hand or buying a static file, your software asks for a record and gets back the registered name, address, registration number, industry code, size, directors and ownership.

The CompanyData API covers 375 million businesses in 200+ countries, sourced from official trade registers rather than inferred from websites.

It depends how much ground you need to cover. A national register API, such as Companies House or the Handelsregister, is free and authoritative but stops at one country and rarely holds contact details or structured financials.

The CompanyData API gives you one endpoint and one schema across every market, so you do not have to build and maintain a separate integration per country. Start with the quickstart or browse the full reference.

Pricing is credit based and scales with volume, so a lookup tool with a few thousand calls a month does not pay enterprise rates. Every account starts with a free trial: 1,000 lookups and 100 exports over two weeks, no card required.

For steady high volume we quote per million records, which lands well below per-call pricing. Tell us your expected monthly volume in the form and you get a concrete number back.

Yes, in two senses. National registers publish free APIs, and we run free trial access with 1,000 lookups so you can test real responses before committing.

What free register APIs do not give you is coverage beyond one country, contact details, decision makers, or a single schema across markets. That is the gap the paid tier fills.

From official trade registers: Companies House, the Handelsregister, the KVK, the KBO, Sirene, and roughly 1,200 more sources worldwide. Every field has a documented origin and a lawful basis, and we hand that documentation over on request.

This is the main difference with providers that infer firmographics from websites and social profiles. Registry data does not go stale the moment a website is redesigned, and it holds entities that have no web presence at all.

Over 200, with the same request shape and the same response schema everywhere. Coverage per country reflects what the local register publishes, so field completeness varies: we are transparent about that per market rather than claiming uniform depth.

Country register pages such as Companies House, Sirene and CVR show exactly what is available locally.

Yes, that is one of the most common uses. Send a company name, domain or registration number and get back the full record to write into Salesforce, HubSpot or your own system. Records can be refreshed on a schedule so your CRM does not drift.

Matching handles the awkward cases: legal form suffixes, trade names and multiple entities at one address.

Yes. Because records come from the register, they carry what a Know Your Business check needs: legal name, registration number, status, registered address, directors and ownership structure up to the ultimate beneficial owner where the register publishes it.

See the KYB API and KYC API pages for the compliance-specific endpoints.

It is a REST API returning JSON, authenticated with an API key in a header. Most teams have a first live call inside an afternoon; the quickstart walks it in five minutes. Average response time is under 200 ms.

There are SDKs for Python and JavaScript, and connectors for Salesforce, Zapier and webhooks if you would rather not write the integration yourself.

Yes. The data is business information from public registers with a documented source and lawful basis, which is what a data protection officer will ask to see. GDPR applies in Europe and the UK, CCPA in the United States.

Where records contain personal data, such as director names, we supply the provenance and the basis for processing it.
