curl -X POST https://api.viddyscribe.com/enterprise/api/generate_ad_audio \
  -H "X-API-Key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "input": {
      "type": "media_id",
      "media_id": "550e8400-e29b-41d4-a716-446655440000"
    },
    "generation_config": {
      "language": "en-US"
    }
  }'

​
2. Using a Public URL

curl -X POST https://api.viddyscribe.com/enterprise/api/generate_ad_audio \
  -H "X-API-Key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
