The Faseeh API uses a credit-based system with concurrent request limits to ensure fair usage and optimal performance for all users.

​
Concurrent Requests

For streaming text-to-speech requests, Faseeh enforces concurrent request limits based on your subscription plan. This ensures stable performance and prevents system overload. Concurrent Request Limits by Plan:
  • Basic: 2 concurrent requests
  • Starter: 5 concurrent requests
  • Growth: 10 concurrent requests
  • Scale: 20 concurrent requests
  • Enterprise: Unlimited concurrent requests
When you exceed your concurrent request limit, you’ll receive a 42901 error (ConcurrencyLimitError). You can either wait for existing requests to complete or upgrade your plan to increase your limit.

​
Best Practices

  1. Monitor your usage: Check your credit balance and concurrent request limits regularly
  2. Plan ahead: Consider your usage patterns when selecting a subscription plan
  3. Handle rate limits: Implement retry logic with exponential backoff for 429 errors
