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 '{
