}FAQ
What does the KYC Agent check?
The KYC Agent runs five checks in a single call: Companies House company status and profile, VAT number validation against HMRC, director and officer research with AML risk flag detection, registered address validation against Royal Mail PAF, and an AI-generated risk assessment. The response is structured JSON with a decision status, risk level, plain-English summary, and risk flags array.
What data sources does it use?
Companies House public API (authoritative UK company registry), HMRC VAT validation service, Royal Mail Postcode Address File (PAF) via the APITier postcode infrastructure, and Claude AI for risk reasoning and summary generation. All company and director data comes from official government sources.
Can I pass a company number instead of a name?
Yes. You can pass a Companies House registration number (e.g. "03977902"), a company name (e.g. "Google UK Limited"), or a VAT number (e.g. "GB123456789"). The agent resolves the correct entity from whichever identifier you provide.
What AML risk flags does the agent return?
Risk flags include: dissolved company, newly incorporated (< 6 months), address not found in PAF, VAT mismatch, overdue accounts, director with high directorship count (> 10 active), director of dissolved companies (≥ 3 in history), currently at insolvent company, address cluster (3+ companies share a postcode), and mass registration address (5+ companies share a postcode).
How accurate is the director research?
Director data comes directly from Companies House — the same source used by law firms and financial institutions. The agent returns full appointment history including all current and past roles, resigned dates, and company status at each appointment. For ambiguous names (multiple people), the agent returns the top candidates and flags ambiguity.
Does it work for Scottish and Welsh companies?
Yes. Companies House covers all UK registered companies including those registered in Scotland (SC prefix) and companies limited by guarantee. The address validation covers all UK postcodes including Scottish and Welsh postcodes via Royal Mail PAF.
How does pricing work?
KYC Agent verifications are billed as credits from your APITier credit balance. Credits have 12-month validity with no monthly subscription. See the pricing page for current credit pack rates. Free credits are included when you sign up to test the integration.
Is there an SLA?
Yes. The KYC Agent is hosted on AWS (EU-West-1) with 99.9% uptime SLA. Response times are under 5 seconds at the 95th percentile. The agent makes multiple upstream calls in parallel — Companies House, HMRC, PAF — to keep latency as low as possible.
