What you can build

Risk checks where the work already happens

Your team should not have to leave the order screen to find out whether a customer can pay.

Credit decisions at the point of sale

Show a recommended credit limit and the latest accounts on the quote or order, so terms are set on evidence.

Customer and supplier onboarding

Confirm a company exists and is active, see who runs and controls it, and verify the person in front of you in the same flow.

Portfolio monitoring

Add every account in your ledger to monitoring and collect the alerts: court judgments, insolvency, overdue accounts, director changes.

CRM and ERP records that stay right

Fill in and refresh company name, status, registered address and industry codes from the official record instead of by hand.

Compliance checks

Screen directors against the disqualified register, check for insolvency and charges, and keep a reference for each identity lookup.

AI agents and automation

Give an AI agent one link and it has the whole reference. Useful for credit-control assistants and automated supplier reviews.

The data

One key, the whole picture of a company

The API returns the same data your team sees in the AlertFlag console, as JSON.

  • Company profile. Status, type, registered address, industry codes, filing dates.
  • Financials. Revenue, profit, assets and ratios, year by year.
  • Recommended credit limit. A figure in pounds with the reasoning behind it.
  • People. Officers, persons with significant control and disqualified directors.
  • Warning signs. Charges, insolvency cases and filing history.
  • Search. Companies and directors in the UK, and companies in other countries.
  • Monitoring and alerts. Start, stop and list monitoring, and read new alerts.
  • Identity checks. Person Verify and IDV Premium, on Enterprise.
Identity Verification

Verify the person, not just the company

Run identity checks from your own sign-up or onboarding flow, in support of your AML and KYC duties. The answer comes back in the same call, with a reference to keep on file.

  • 2 billion+ consumer profiles. IDV Premium matches a person globally, across 48 countries.
  • Person Verify. Confirm a name at an address in the UK, Germany, France and Australia.
  • A clear answer. One match level and a field-by-field breakdown your system can act on.
  • Private by design. Personal details travel in the request body, never in the URL, and are not kept in the request log.

Identity checks through the API are part of the Enterprise plan.

FAQ

Questions about the API

Which plans include the API?

Professional and Enterprise. Professional includes 100 requests a month and Enterprise 1,000. Both come with the full console, so your team can look at the same companies your systems are checking.

What if we need more than 1,000 requests a month?

Tell us the volume you expect and we will set a higher allowance on your Enterprise account.

What data can we pull?

For UK companies: the company profile, financial accounts, a recommended credit limit, officers, persons with significant control, charges, filing history and insolvency. You can also search companies, directors and the disqualified directors register, search companies in other countries, and manage monitoring and read alerts.

Do you cover companies outside the UK?

Yes, for search. International Search covers over 100 million firms worldwide. It finds companies by name in another country and returns their website, industry, size and location. Financial accounts and credit limits are for UK companies.

Can we run identity checks through the API?

Yes, on Enterprise. Person Verify confirms a name at an address in the UK, Germany, France and Australia. IDV Premium matches a person against 2 billion+ consumer profiles across 48 countries for AML and KYC.

How long does it take to integrate?

It is a REST API that returns JSON, with one key sent in a header. Most teams make their first call the day they sign up. There is an OpenAPI description to generate a client from, and a single reference file you can hand to an AI coding agent.

Is there a minimum term?

No. Plans are monthly or yearly and you can cancel any time from your account.
