On September 23, 2026, X announced an updated livestream API that lets third-party video platforms drive broadcasts on X directly. The company said the API was rebuilt from the ground up, with expanded functionality so creators can go live on X through the streaming provider of their choice rather than only inside X's own tools.
Per X's description, the rebuilt API covers the full broadcast lifecycle: managing persistent RTMP streams, creating, publishing, and monitoring broadcasts, scheduling broadcasts ahead of time, reading and responding to live chat, and moderating that chat — including muting and removing viewers. In practice that means the encoders and studio tools creators already use to stream elsewhere can now stand up, schedule, and manage an X broadcast programmatically, and pull the live conversation into their own dashboards.
This is a separate move from X's built-in Live Studio, which launched in early July 2026 as a first-party command center for streaming on X. Where Live Studio put the broadcast controls inside X's own Creator Studio, the updated API opens those controls to outside developers and streaming services. Treat the exact access requirements, rate limits, and provider list as an early snapshot — X's own developer documentation is the source of truth as the rollout settles.
The most useful new capability here is quiet: broadcasts can now be scheduled through the API. A scheduled stream is a dated event, and a dated event has a runway — the days before it where you build anticipation, and the days after where you harvest the replay. Kompozy is built for both ends of that runway, neither of which the streaming stack itself touches.
Before you go live, point Kompozy at your stream topic and it generates the promo cadence: Text Posts and a Carousel teasing the session, a Quote Graphic with the date and time, and a short Listicle Video previewing what you'll cover — all sized per platform and scheduled by Autopilot across your eight social platforms plus a blog and newsletter so people actually show up. After the broadcast, drop the recording in and Clipped Shorts finds the strongest moments and cuts them to vertical with branded captions via HyperFrames, while the same session becomes a recap Blog Article, more quote cards, and an Email Newsletter — every piece held to one voice by your Persona Brief. And when the API update is itself the story, Kompozy turns this news into a package: an explainer blog that can rank, a carousel of the new features, and native posts, published everywhere from one queue while the change is fresh.
On September 23, 2026, X announced a rebuilt livestream API that lets third-party video platforms drive broadcasts on X. It supports managing persistent RTMP streams, creating, publishing, and monitoring broadcasts, scheduling them ahead of time, and reading, responding to, and moderating live chat — so outside encoders and streaming services can run an X broadcast directly.
X Live Studio, launched in early July 2026, is X's own built-in command center for going live inside Creator Studio. The September 2026 API update opens those broadcast controls to third-party developers and streaming services, so the tools you already use elsewhere can create, schedule, and manage a stream on X programmatically.
Yes. Per X's description of the rebuilt API, broadcasts can be created and scheduled ahead of time, alongside publishing, monitoring, and live-chat moderation. Exact access requirements and any subscription gating are still settling, so confirm current terms in X's developer documentation before building around it.
The API runs the live broadcast but does not clip or cross-post the replay. Bring the recording into a content engine like Kompozy: Clipped Shorts detects the best moments and cuts them to vertical with branded captions, and the same session becomes a recap blog, quote cards, a carousel, and a newsletter that Autopilot publishes across your other platforms.
