What is the LTX 2 API?

LTX 2 is a real-time-oriented video family from Lightricks. Muapi brings Pro, Fast, 19B, 2.3, and 2.5 variants behind the same request-ID and polling workflow.

Use text-to-video for prompt-first shots, image-to-video for controlled motion, video extension for continuity, and lip sync when audio should drive a performance.

LTX 2 API capabilities

Prompt-to-video

Create clips with LTX 2 Pro, Fast, 2.3, and 2.5.

Image-to-video

Animate a starting frame while preserving the subject and composition.

Video extension

Continue an existing clip with ltx-2.3-video-extend.

Lip sync

Use LTX 2 19B or 2.3 lip-sync endpoints for audio-driven performance.

Quick start — LTX 2 API

Submit an LTX generation with JSON and poll the returned request ID using Muapi's shared result endpoint.

1. Submit an LTX job

curl -X POST https://api.muapi.ai/api/v1/ltx-2-pro-text-to-video \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"prompt":"A slow dolly through a greenhouse after rain","duration":6}'

# Response: {"request_id":"REQUEST_ID"}

The example uses LTX 2 Pro text-to-video; use any listed LTX slug for another mode.

2. Poll the result

curl https://api.muapi.ai/api/v1/predictions/REQUEST_ID/result \
  -H "x-api-key: YOUR_API_KEY"

Read the completed video URL from the result response.
