Rate Limits & Quotas

AudioSpliter enforces rate limits and usage quotas to ensure fair usage and platform stability.

Rate Limits

Rate limits are applied per API key:

Plan	Requests/min	Concurrent Jobs
Free	10	2
Starter	60	5
Pro	300	20
Enterprise	Custom	Custom

Rate Limit Headers

Every API response includes rate limit headers:

X-RateLimit-Limit: 60
X-RateLimit-Remaining: 58
X-RateLimit-Reset: 1711700460

Header	Description
X-RateLimit-Limit	Maximum requests per window
X-RateLimit-Remaining	Requests remaining in current window
X-RateLimit-Reset	Unix timestamp when the window resets

Exceeding Rate Limits

When you exceed the rate limit, the API returns 429 Too Many Requests:

{
  "error": {
    "code": "RATE_LIMITED",
    "message": "Rate limit exceeded. Retry after 32 seconds.",
    "status": 429,
    "retryAfter": 32
  }
}

The Retry-After header is also set.

Monthly Quotas

Each plan has a monthly processing quota measured in minutes of audio processed:

Plan	Monthly Minutes	Overage Rate
Free	60	Not available
Starter	500	$0.02/min
Pro	5,000	$0.01/min
Enterprise	Custom	Custom

Checking Your Usage

Query the Get Usage endpoint to check current consumption:

curl https://api.audiospliter.com/api/v1/billing/usage \
  -H "Authorization: Bearer your_jwt_token"

Best Practices

• Implement exponential backoff when you receive 429 responses.
• Cache job results instead of polling repeatedly.
• Use webhooks instead of polling to reduce API calls.
• Monitor usage in the dashboard to avoid hitting quotas unexpectedly.
