Is there a service for determining content of dubious content?

Question

API

In general, users upload pictures that everyone then looks at. It is necessary to determine the uploaded photo contains boobs or not. Is there any thread library or online service where you can send a picture and get "Ololo, this is 16+" or "Ok, everything is fine"?
On Google Images, it seems to be signed, which is contained in the photo. Maybe there is something on its base?
