What is the LTX API and how do I get started?
The LTX API gives developers direct access to LTX video generation. Use it to integrate text-to-video, image-to-video, and audio-to-video generation into your own products and workflows. Get started in the Developer Console.
LTX-2 model IDs (ltx-2-fast, ltx-2-pro) will stop being supported on August 15, 2026. Switch to ltx-2-3-fast or ltx-2-3-pro before then. From July 15, LTX-2 requests are automatically routed to LTX-2.3 and billed at LTX-2 rates. Find out more.
What is the LTX API?
An API lets your own software send requests directly to LTX and get visuals back — without any manual interaction. Your code sends a request describing what you want (a prompt, an image, an audio file), LTX processes it, and returns the generated output. It's how developers build LTX generation into their own apps, automate production workflows, or handle large volumes of content programmatically.
The API is hosted and run by LTX. You pay per second of video output. See API pricing for current rates, or talk to our team if you're evaluating at scale.
What the LTX API supports
- Text-to-video — generate video from a text prompt
- Image-to-video — animate a starting image
- Audio-to-video — generate video synchronized to an audio track
- Retake — regenerate a segment of an existing video
- Extend — lengthen an existing video
- Video-to-video HDR — upscale SDR video to HDR
The current model family is LTX-2.3, available in two tiers: ltx-2-3-fast for rapid iteration and ltx-2-3-pro for higher-fidelity output.
How to get started
- Go to the Developer Console to create an API key and purchase credits
- Follow the quick start guide in the developer docs to make your first request
Can I test it before integrating?
Yes — the API Playground lets you experiment with prompts and settings before writing any code. Note that generations in the Playground include a watermark.
API billing vs. Studio plans
The LTX API is billed separately from LTX Studio subscriptions. Having a Studio plan doesn't include API access — you purchase API credits independently in the Developer Console. See Understanding LTX API pricing for details.
