Orthogonal is a unified API platform that enables AI agents to discover, access, and pay for dozens of third-party APIs through a single integration. Developers receive one API key, standardized request formats, built-in authentication, and pay-per-request billing, eliminating the need to manage separate vendor accounts. The platform supports use cases such as lead generation, company enrichment, recruiting, web scraping, and business intelligence, while also providing MCP compatibility for AI agent frameworks. Orthogonal aims to simplify agent infrastructure by combining API orchestration, payments, and service discovery into one developer-friendly platform.
