LIFECYCLE ARCHITECTURE

Every decision is traceable, contestable, and replayable

A regex gives you a yes/no. An LLM gives you a score. Vettly gives you a complete decision record that tracks policy version, appeal outcome, and retention status so you're always ready for moderation reviews.

DEVELOPER FIRST

Three integration steps. Six workflows behind the scenes.

You integrate three simple endpoints. Vettly handles filtering, reporting, blocking, appeals, audit trails, and policy versioning for you.

1. Add one moderation call

Call the /v1/check endpoint before content is published.

Policy evaluation, graduated actions, category scoring, and full decision logging.

2. Turn on report + block

Enable user reporting and blocking endpoints.

Report routing, resolution tracking, mutual-block enforcement, and appeals workflow.

3. Ship with audit evidence

Every decision logged with the policy version that produced it.

Decision replay, compliance exports, retention rules, and searchable history.

import { Vettly } from '@vettly/sdk';

// Initialize the SDK
const vettly = new Vettly(process.env.VETTLY_API_KEY);

// Block toxic content before it hits your DB
const decision = await vettly.check({
  content: { text: "Hello world", type: "text" },
  user_id: "usr_123",
  policy_id: "pol_strict_v2"
});

if (decision.action === "block") {
  return res.status(400).json({ 
    error: "Content violates community standards",
    reason: decision.flags[0]
  });
}
