**APIs profiled:** 14

Stream (GetStream.io) provides scalable, API-first infrastructure for in-app chat messaging, activity feeds, audio/video calling and livestreaming, and AI moderation. The server-side platform is a documented REST API (base https://chat.stream-io-api.com for Chat) with JWT authentication, complemented by client SDKs that open a persistent WebSocket connection to receive real-time events - message.new, typing.start, user.presence.changed, reaction.new, notification.* and periodic health.check heartbeats. Products are metered on monthly active users (Chat) and participant minutes (Video), with Free/Maker, Standard (Startup) and Enterprise tiers.
