June 2026: A reimagined API Copilot to answer questions, C# v4 SDKs now support pagination, and response streaming in TypeScript

API Copilot now lives in a dedicated panel beside your docs, so developers can start integrating by asking a question. C# v4 SDKs paginate across four strategies, identify themselves on every request, and attach retry-safe idempotency keys to non-GET calls. TypeScript SDKs stream over Server-Sent Events with a familiar for await…of loop, and Context Plugins can now load your API context into Claude Code, Cursor, and VS Code, even when your SDKs are not published.
