Trade-offs

slower render

Call it from your code

One Varosity key works for every model. Video renders are async — the response has a jobId; poll GET /api/v1/jobs/{jobId} until status is "succeeded", then read outputUrl.

curl -X POST https://varosity.ai/api/v1/video/generate \
  -H "Authorization: Bearer $VAROSITY_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "cinematic aerial of a coastal road at golden hour, slow push-in",
    "modelId": "hunyuan-video-1.5",
    "aspectRatio": "16:9",
    "durationSec": 5
  }'

"Use Varosity with hunyuan-video-1.5 to make a 5-second clip of …"
