What Happens at the Limit

When you reach 60 minutes of processing in a calendar month:

{
  "error": {
    "code": "QUOTA_EXCEEDED",
    "message": "Free tier quota exceeded. Upgrade to continue processing.",
    "status": 402
  }
}

Your existing jobs and segments remain accessible until the 24-hour retention window expires.

Resetting

The quota resets on the first day of each calendar month at midnight UTC.

Upgrading

When you are ready for more capacity, upgrade to a paid plan:

curl -X POST https://api.audiospliter.com/api/v1/billing/subscribe \
  -H "Authorization: Bearer your_jwt_token" \
  -H "Content-Type: application/json" \
  -d '{"planId": "plan_starter"}'

Or visit Billing > Upgrade in the Dashboard.

Tips for Staying Within Free Limits

• Use short test files during development
• Delete completed jobs promptly to keep your workspace clean
• Use the sandbox (as_test_ API keys) for integration testing without consuming quota
• Monitor usage via the Get Usage endpoint
