# Company Search API
> Advanced filtering transforms generic databases into laser-targeted prospect lists that sales teams actually convert. The Company Search API queries CUFinder's 85M+ company profiles using multiple parameters—including location, industry, employee size, funding, and founding year—returning filtered business data with 96% confidence scores. Built for developers creating prospecting tools and market intelligence platforms, this RESTful endpoint delivers granular company matches that power account-based marketing, lead generation, and competitive analysis workflows across your sales stack.
