Our proxy service has no limit on the number of requests or concurrent sessions, so you are free to make multiple requests or process multiple sessions at the same time. 

This provides greater flexibility and scalability for your application or service, enabling you to cater to businesses of different sizes and needs. Also, our API request frequency is limited to one every 2 seconds. 

This means that your application or service needs to ensure that the interval between two requests is at least 2 seconds when making API requests. Such a limit helps to balance the server load and ensures that the server can provide a stable and efficient response. 

If you have any other needs or require further assistance, we encourage you to contact our customer service team. Contact is email service@pyproxy.com.
