AI app builders - Moderation API

App builders write the code for you, so you add moderation with a prompt. You do two things yourself: store the API key as a secret, and paste the prompt.

1. Store the API key as a secret

Copy your project’s API key from the dashboard. Store it as a secret named MODAPI_SECRET_KEY. Do not paste the key into the chat.

Builder	Where to add the secret
Lovable	Cloud → Secrets. The key is available to Edge Functions only.
v0	The Vars panel. Do not add the `NEXT_PUBLIC_` prefix.
Bolt	The Secrets section in the database settings. The key is available to server functions.
Replit	The Secrets tool. When you publish, add the key to the deployment secrets too.

2. Paste the prompt

Add content moderation with Moderation API to every place where users create
content (posts, comments, messages, profiles).

- Call it from server code only (an API route, server action, edge or server
  function), never from the browser. Read the key from the MODAPI_SECRET_KEY
  secret. Never put the key in client code.
- Send each piece of content before you save it:
  POST https://api.moderationapi.com/v1/moderate
  Authorization: Bearer <MODAPI_SECRET_KEY>
  Body: {"content": {"type": "text", "text": "<the text>"}, "authorId": "<user id>"}
- Read recommendation.action from the response:
  - "allow": save and publish.
  - "review": save it but do not publish it yet. A moderator decides.
  - "reject": do not save it. Show the user a short, neutral message.
  Treat any other value as "review".
- If the request fails, save and publish the content, so users are not blocked.

3. Test it

Post a message that should be rejected, such as a scam or a threat, and check that your app blocks it. The request appears in the dashboard. To act on decisions that moderators make later in the review queue, add webhooks.
