api.limitguard.ai · 18 paid endpoints · listed 2026-10-27
Lead verify for one NL or BE sales lead: is it a real, active company? Checks the KVK or KBO register and cross-checks what the lead holds: VAT with VIES, mail server and disposable domain, IBAN country and bank (not the holder), and the company name against the OFAC, EU and UN sanctions lists. Returns a verdict, a 0-100 lead score and flags, each with one action. An input not given is not checked.
