Rate limits apply per API key. Contact sales@audixa.ai for custom enterprise limits.

​
Rate Limit Headers

Every API response includes headers showing your current rate limit status:
HeaderDescription
X-RateLimit-LimitMaximum requests allowed per minute
X-RateLimit-RemainingRequests remaining in current window
X-RateLimit-ResetUnix timestamp when the limit resets
Example response headers: 
X-RateLimit-Limit: 120
X-RateLimit-Remaining: 115
X-RateLimit-Reset: 1702300800

​
Handling Rate Limits

When you exceed the rate limit, the API returns a 429 Too Many Requests error: 
{
  "detail": "Rate limit exceeded. Please retry after 30 seconds."
}

​
Retry Strategy

Implement exponential backoff to handle rate limits gracefully: 
import time
import requests

def make_request_with_retry(url, headers, json_data, max_retries=5):
    for attempt in range(max_retries):
        response = requests.post(url, headers=headers, json=json_data)
        
        if response.status_code == 429:
            # Get retry delay from header or use exponential backoff
            retry_after = int(response.headers.get("Retry-After", 2 ** attempt))
            print(f"Rate limited. Retrying in {retry_after} seconds...")
            time.sleep(retry_after)
            continue
        
        return response
    
    raise Exception("Max retries exceeded")

Best Practices

Batch Requests

Combine multiple short texts into fewer requests when possible.

Implement Backoff

Use exponential backoff when retrying failed requests.

Monitor Usage

Check rate limit headers to track your usage.

Cache Results

Store generated audio to avoid regenerating the same content.

Need Higher Limits?

If you’re hitting rate limits regularly, consider:
  1. Upgrading your plan for higher per-minute limits
  2. Contacting sales for custom enterprise limits
  3. Optimizing your code to reduce unnecessary requests
