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

const result = await vettly.check({
  content: userInput,
  contentType: 'text',
  policyId: 'default',
});

if (result.action === 'block') return res.status(400).end();
Example response
json
{
  "flagged": true,
  "action": "block",
  "categories": {
    "harassment": 0.93,

Compared to calling provider APIs directly

Vettly normalizes responses across providers and adds retries, evidence, and audit trails out of the box.
