const vettly = new Vettly({ apiKey: process.env.VETTLY_API_KEY! });

export async function POST(req: Request) {
  const { content } = await req.json();
  const result = await vettly.check({ content, contentType: 'text', policyId: 'default' });

Example response

Compared to rolling your own classifier

Vettly returns decisions, not raw scores - your route handler stays a few lines instead of a classification pipeline.
