@kirby Hello! It seems like you're encountering a CORS (Cross-Origin Resource Sharing) policy issue, which is a common web security measure to prevent unwanted cross-origin requests. This error does not necessarily indicate that you've been rate limited or blocked by Vapi, but rather that there's a mismatch or absence of CORS headers in the API response that's required for browser-based requests. To address this issue, you can: 1. Check if the CORS policy is correctly set up on your server to include the domain

https://app.tryaptitude.ai

in the

Access-Control-Allow-Origin

header. 2. Ensure that your API requests to Vapi are configured correctly and that you are passing the necessary headers. 3. If you're using a server or a proxy, you can configure it to add the correct CORS headers to the response before it reaches the client. Regarding upgrading to a pro plan or enterprise plan, you would need to contact Vapi's sales or support team to discuss the available options and find a plan that suits your startup's needs. They can also provide you with more information on rate limits and how to handle a higher volume of API requests. If you need further assistance with the CORS issue or have any other questions, please let me know!
