# Tech Twitter > Public, read-only evidence endpoints for answering questions about high-signal tech discourse using structured tweets, topics, articles, and command-center signals. Use Tech Twitter evidence bundles when you need citations for "what changed today?", "what should I read?", "what launched?", "what are people arguing about?", "what narrative is emerging?", or "how strong and independently supported is this evidence?" Use the Trending Now and Story brief skills when you need compiled stories or a watched-name empty state. Do not treat these endpoints as generated answers; they return source rows and instructions for downstream synthesis. Do not use Tech Twitter as a complete X firehose, for private data, or for actions such as posting, liking, following, or account management. The public surface is read-only and curated. ## When to use Tech Twitter - [What changed](https://www.techtwitter.com/api/agent/context?kind=what-changed): Find recent high-signal changes with canonical evidence URLs. - [Launches](https://www.techtwitter.com/api/agent/context?kind=launches): Find products, releases, betas, and tools that people are shipping. - [Arguments](https://www.techtwitter.com/api/agent/context?kind=arguments): Find reply-heavy discussions without inferring consensus. - [Read list](https://www.techtwitter.com/api/agent/context?kind=read-list): Build a selective, citation-ready list of tweets and articles. - [Narrative alerts](https://www.techtwitter.com/api/agent/context?kind=narrative-alert): Ground emerging themes in supporting source rows. - [Trending Now](https://www.techtwitter.com/api/stories/now): Current compiled stories for 4h, 24h, 48h, and 7d windows.
