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": "heygen-video-translate",
    "aspectRatio": "16:9",
    "durationSec": 5
  }'

Or ask your agent

Connect Claude, Cursor, or any MCP client to https://varosity.ai/api/mcp with your key, then say:

"Use Varosity with heygen-video-translate to make a 5-second clip of …"
