One of my favorite verticals that I've worked on, and there's so much more to come.
A world-class streaming platform needs a world-class API to match. Now it's here.
Tell your favorite streaming software company to get integrated today.
X Livestream API has been rebuilt from the ground up.
Your entire broadcast lifecycle on X can now be powered by our API: go live, schedule broadcasts, run and moderate chat, and get live events for alerts and overlays. Available now. 🚢

On top of the included credits to Grok Bot users, this week we started giving $20 of monthly X API credits to all Premium+ users.
Grok Bot now has improved support for X!
When you connect your X profile, a developer account will be automatically created with some included credits.

𝕏 Chat is a full rewrite of DMs on 𝕏 and will replace legacy DMs over time
That only works if builders can come along. Businesses ran support & automation on the DM API for years, but none of it works with encrypted messages
𝕏 Chat needed an API of its own. Today it has one

We've completely rebuilt the Android X app from the ground up.
It's faster, smoother, and more reliable than the old version in every way. We modernized the foundation so everything just feels better: scrolling, loading, notifications, you name it.
