Next.js Profanity Filter

Use a Next.js Route Handler so your API key stays server-side while your client components call your own endpoint.

Quick start in Next.js

// app/api/moderate/route.ts
export async function POST(req: Request) {
  const { text } = await req.json();
  const r = await fetch("https://api.theprofanityapi.com/v1/check", {
    method: "POST",
    headers: {
      Authorization: `Bearer ${process.env.PROFANITY_API_KEY}`,
      "Content-Type": "application/json",
    },
    body: JSON.stringify({ text, context: "comment", mode: "balanced" }),
  });
  return Response.json(await r.json());
}

Why context-aware matters

A plain word list flags "this game is sick" or medical text full of anatomical terms. The Profanity API runs a five-layer pipeline that scores intent, so "die" in a gaming taunt and "die" in a real threat are handled differently. Pick a context and the engine adjusts strictness automatically.
