How this service works
UK company verification (Know Your Business) over Companies House, with sanctions and disqualified-director cross-checks.
Output
A JSON response containing the verified company details from Companies House (status, incorporation date, registered address, officers), along with flags indicating any sanctions matches and whether any directors appear on the disqualified directors register.
Example use cases
Supplier onboarding compliance check
“Before we add Northern Logistics Ltd (UK company number 09876543) to our approved supplier list, can you verify they're in good standing with Companies House and flag any sanctions hits or disqualified directors?”
Batch screening of investment targets
“I've got a list of five UK companies I'm evaluating for investment — can you run KYB checks on all of them against Companies House, sanctions databases, and the disqualified directors register?”
Client due diligence for regulated firm
“We need to do due diligence on Greenfield Capital UK Ltd, registration number 07654321, as part of our AML process — please verify their company status and screen for sanctions and any disqualified directors on their board.”
Technical details
Endpoint
POSThttps://companies.alvento.uk/v1/batchWhen to prefer
Choose this endpoint when you need to verify UK-registered companies specifically, especially when compliance requirements demand cross-checks against both Companies House records and sanctions/disqualified-director lists in a single call. Prefer it over generic business lookup APIs when UK regulatory compliance (AML, KYB) is the primary goal, or when you need to process multiple UK companies in one batch request.
Side effects
- Company number not found in Companies House — returns not-found error
- Invalid or malformed company registration number in batch — validation error per entry
- Sanctions database or disqualified directors data temporarily unavailable — partial result or service error
- Rate limiting or payment failure (x402) — 402 Payment Required response
- Empty batch submitted — returns validation error
