Why Add a Content Moderation API to Node.js Apps

Node.js powers a large share of the products where user-generated text appears first: chat rooms, comment threads, forums, marketplace listings, community feeds, and support inboxes. In nearly all of those systems the critical moment is the same. A string arrives from a user, and your handler has to decide whether it can be saved, published, or broadcast to everyone else.

Adding a content moderation API to a Node.js service is mostly an HTTP integration problem. You send a text to an endpoint, you get JSON back, and you branch on it. There is no model to host, no word list to curate, and no scoring curve to calibrate.
