Make your first request

Text-to-Video

Generate a video from a text prompt:

Request
$curl -X POST https://api.ltx.io/v1/text-to-video \
>  -H "Authorization: Bearer YOUR_API_KEY" \
>  -H "Content-Type: application/json" \
>  -d '{
>    "prompt": "A majestic eagle soaring through clouds at sunset",
>    "model": "ltx-2-5-pro",
>    "duration": 8,
>    "resolution": "1920x1080"
>  }' \
>  -o video.mp4

The API returns the generated video file directly as an MP4.

Image-to-Video

Transform a static image into a dynamic video:

Request
$curl -X POST https://api.ltx.io/v1/image-to-video \
>  -H "Authorization: Bearer YOUR_API_KEY" \
>  -H "Content-Type: application/json" \
>  -d '{
>    "image_uri": "YOUR_IMAGE_URI",
>    "prompt": "Clouds drifting across the sky as the sun sets slowly",
>    "model": "ltx-2-5-pro",
>    "duration": 8,
>    "resolution": "1920x1080"
>  }' \
>  -o video.mp4

Replace YOUR_IMAGE_URI with a publicly reachable HTTPS URL to your image. You can also upload the image and pass the returned ltx:// URI, or inline it as a base64 data URI — see Input Formats.

Response

Successful requests return:

  • Body: The generated video file (MP4 format)
  • Headers:
    • Content-Type: video/mp4
    • x-request-id: Unique identifier for tracking

Going to production? Switch to the async API — submit a job, poll for the result. Avoids long-lived connections and timeouts on heavier requests.
