# API Marketplace Connect any API in 30 seconds. Browse popular APIs, click Connect, and start calling. The marketplace is a curated catalog of popular APIs with pre-filled configuration. Select an API, add your credentials, and get a connection ready for proxy calls. ## How It Works 1. Browse — find the API you need by category or search 2. Connect — click Connect, provide your API key or token 3. Call — use /proxy/{connection_id}/... to call any endpoint Your credentials are encrypted with AES-GCM-256 and never exposed in responses. ## Available APIs ### AI & Machine Learning
