What do you think about my product idea?

Hello everyone! I have a product idea, which I came out of my problems. Imagine an analytics app that doesn't depend on the platform (platform-independent), gives you an API endpoint, and you just call it when an event occurs on your website. Let's say someone clicks the "Add to cart" button, you just need to send a request to the API route, and it will track it and add it to your events so that you can track events on your dashboard. Of course, there will be helpers/scripts that users can use on different platforms, but the main point is that you don't need to use them as a boilerplate to execute it. You don't need to install the npm package, etc. It also gives you the freedom to track events in a way you want. What do you think about this idea? I am ready for harsh feedback (realistic ones) from industry experts.
