Luma AI API

1. Send model ray-3.2 and type video, with resolution and duration inside video. Older model names are rejected
2. Poll GET /v1/generations/{id} until completed or failed, then copy the presigned URL
3. On 429, read detail. Rate limit exceeded means wait Retry-After, Too many concurrent jobs means wait for a job to finish
4. Use keyframes with keyframe_indexes for 10 second clips. start_frame and end_frame only work at 5 seconds

PixVerse API

1. Generate a new UUID for Ai-trace-id on every new submit. Reuse it only to fetch the same job again
2. Poll the result endpoint. Status 1 is done, 5 generating, 7 moderation failure, 8 failed
3. Moderate prompts before calling. Repeated status 7 results can suspend the key
4. Use model v6 or c1 for new work. Older model tables still sit in the docs
