API To Find The Right Amazon Categories For A Product From Title And Description. Feedback Appreciated

I am new into the SaaS/API world and decided to build something on the weekend so I built an API that let you put a product title and an optional description and it gives the relevant Amazon categories. Is this something you guys use or need? If yes, what do you look for in such an API? I’m playing with it so far and put it a version of it out there : https://rapidapi.com/textclf-textclf-default/api/amazoncategoryfinder

Let me know what you think. Your feedback is greatly appreciated
