Is there a service for analyzing text for correctness and other filters?

Question

Clustering

Greetings to all who come!
Tell me if there are services (preferably free) that can analyze texts of different sizes. For example, a user writes some text in my service and in order not to process it for me and write my own solution, then I send the text through the api, and the result of the analysis is returned to me, which contains: language, the presence of swear words, the presence of some topics, which I forbid (politics, porn words, racism and more), mentioning not recommended brands / products, advertising anything, and getting a certain "weight" of the text or a conclusion from the service for maximum correctness.
You can write your own, but it's a gigantic job to write such a handler for all the languages ​​of the world, plus keeping it up to date ... not so easy. Maybe ready?
