LTX-2.5 Fast

1. Integration status

This video reference has no verified model mapping in the current Lithovas catalog. The page path lightricks/ltx-2.5/text-to-video/fast is a documentation identifier, not an enabled API model ID.

Check the authenticated model list for availability to your API key. Catalog presence does not guarantee capacity or permission for every account.

curl https://api.seedance.ch/v1/models \
  -H "Authorization: Bearer $LITHOVAS_API_KEY"

2. Authentication

Use a Lithovas API key in the Authorization header. Keep it on your server, not in browser code or source control.

export LITHOVAS_API_KEY="YOUR_API_KEY"

3. Request contract

No enabled video submission contract is mapped to this reference. No generation endpoint, model ID, or parameter schema is published here until that mapping is verified.

Do not send this page path as the model value. In particular, an image or workflow page must not inherit the video endpoint merely because it shares a layout.

4. Results and polling

No video task or output protocol is currently mapped to this reference. Follow the selected model’s documented response and result protocol after an integration is available; do not assume video polling or MP4 output.

This documentation stays readable independently of generation availability.

5. Errors and next steps

For authenticated API calls, check the returned error message: 401 indicates invalid or missing credentials; 429 calls for backoff. For unavailable-model or validation failures, verify the exact model and its supported contract before retrying.

Use the live catalog to choose an integrated model. Model-local request history is separate from these documentation examples.
