Unified.to (unified-to)

Unified is a real-time unified API platform that provides access to over 360 integrations across 22 categories for B2B SaaS and AI-native products. Unlike traditional integration platforms that cache or sync data periodically, Unified operates with a pass-through architecture where every request hits the source API live, ensuring no stale data and eliminating the need for storage of customer information.
