Factline checks companies, people and payees against official records before you onboard a client or pay an invoice. One API and remote MCP server for AI agents and apps: company lookup in 9 national registers plus GLEIF, sanctions screening (EU, UN, UK, US OFAC) and PEP, EU VAT (VIES), IBAN and Peppol checks, a supplier invoice check that puts a payment on hold when the bank details changed, and a pay guard for x402 agent payments. For Dutch firms under the Wwft and the EU AMLR there is a client file app: screen a business client or a private person, record the risk rating and your decision, and export a Dutch audit PDF. Every paid answer comes with a signed receipt. Pay per call over x402 (USDC) or use an API key; a free trial and a free pilot are available.
