Factline - 2026 Pricing, Features, Reviews & Alternatives

Factline is a cloud-based REST API platform designed for developers, compliance teams, and businesses that require automated company verification and KYC checks across European markets. The API queries official national business registers across multiple countries, including France, Estonia, Norway, Finland, Czechia, Slovakia, Poland, and the United Kingdom, returning structured data such as legal name, registration status, registry ID, legal form, registered address, and founding date. Access is available via API key or through x402 micropayment protocol on a pay-per-call basis at 0.008 USDC, with no subscription required.

A single API call can combine company verification with sanctions and PEP screening, VAT validation, email verification, and phone checks, reducing integration overhead for compliance workflows. Additional capabilities include IBAN validation, Dutch bankruptcy checks (Wwft client files), and payee verification via the x402 protocol. A free preview endpoint is available without full API key commitment, allowing teams to evaluate data quality and coverage before committing to integration.

Factline targets fintech, legal, financial services, and any industry subject to KYC or anti-money-laundering (Wwft) obligations. A dedicated llms.txt endpoint supports programmatic consumption by AI agents and large language model-based workflows, extending the platform's utility to automated compliance pipelines and AI-driven due diligence processes.
