    As many as you want! However, there is a fair use policy of 100,000 messages per week per instance (soft limit). This limit is set to prevent abuse of our proxy server and hurt our bandwidth usage. If you reach this limit, we'll contact you for a specialized plan.

    Your API key is stored securely in our database, encrypted and is not shared with anyone. When your users send messages using your Chat instance, the requests are sent to our server, then we will use your API key to get the response from ChatGPT/Anthropic.
