Types of limits
Portrix applies three categories of limits to your API key:- Requests per minute (RPM): The maximum number of individual API calls you can make per minute. Each call to
/v1/chat/completions,/v1/embeddings, or any other endpoint counts toward this limit. - Tokens per minute (TPM): The total number of tokens — input plus output — consumed across all requests in a rolling one-minute window.
- Daily token quota: The total number of tokens you can consume in a 24-hour period, determined by your plan. This resets at midnight UTC.
429 Too Many Requests response.
Limits by plan
The following table shows representative limits for each Portrix plan. Your actual limits are displayed in real time on the Usage page in the dashboard.Limits shown above are representative defaults. Your specific limits may vary based on your plan configuration. Always check the dashboard for your exact quotas.
Checking your usage
To view your current usage and remaining quota:- Go to app.portrix.ai and sign in.
- Navigate to Usage in the left sidebar.
- Select a time range to view RPM, TPM, and token consumption over time.
Handling rate limit errors
When you hit a rate limit, Portrix returns a429 status code with a Retry-After header indicating how many seconds to wait before retrying. Implement exponential backoff in your application to handle these responses gracefully.
Increasing limits
If you need higher limits than your current plan provides, you have two options:- Upgrade your plan: Go to Settings > Billing in the dashboard and select a higher tier. Limits increase immediately upon upgrade.
- Enterprise plan: For custom RPM, TPM, or daily quota requirements, contact the Portrix team at [email protected] to discuss an Enterprise plan tailored to your usage patterns.
