API keys

All Deepdub API requests require authentication via an API key passed in the x-api-key header. 
curl -X POST https://restapi.deepdub.ai/api/v1/tts \
  -H "Content-Type: application/json" \
  -H "x-api-key: YOUR_API_KEY" \
  -d '{ ... }'

​
Key format

API keys follow the format dd-{random_characters}{checksum}, where:
  • The key always starts with the dd- prefix
  • The last 8 characters are a checksum for validation

​
Obtaining an API key

Contact [email protected] or visit your Deepdub dashboard to generate an API key.

​
Security best practices

Never expose your API key in client-side code or public repositories. Always store keys in environment variables or a secrets manager.
  • Store API keys in a secrets manager (e.g., AWS Secrets Manager, HashiCorp Vault, GCP Secret Manager)
  • Rotate keys periodically
  • Use different keys for development and production environments

​
Rate limits

API requests are subject to rate limiting based on your subscription plan:
Limit typeDefault
Concurrent requests per customer5
Concurrent requests per IP3
Rate limit errors return a 429 status code or a WebSocket error with errorType: "RateLimit".

​
Credits

TTS generation consumes credits based on the duration of generated audio. If your account runs out of credits, requests will return an InsufficientCredits error. Check your credit balance in the Deepdub dashboard, or contact support to upgrade your plan.
