Frequently Asked Questions

Everything you need to know before you start building.

Where does the data come from?

All data is sourced directly from Companies House, the UK's official registrar of companies. We ingest filings continuously and normalise them into a consistent JSON schema — no scraping, no third-party aggregators.

How up to date is the data?

Company status and officer information is updated as filings appear on the Companies House register. Financial data reflects the most recently filed annual accounts, which companies are required to submit each year.

What counts as one request?

Each call to any API endpoint counts as one request — whether you're fetching a company profile, financials, officers, or filing history. There are no partial or weighted requests.

What happens if I exceed my monthly limit?

Requests beyond your plan's allowance are rejected with an HTTP 429 response. We don't automatically charge for overages — simply upgrade your plan to increase your limit.

Do I need a credit card to sign up?

No. The Free plan requires no payment details. You only need to provide billing information when upgrading to a paid plan.

Can I use the data commercially?

Yes. All paid plans include a licence for internal commercial use. You may not resell or sublicense raw API access to third parties. See our Terms & Conditions for full details.
