Getting a Civitai API Key

An API key is required for authenticated requests: favorites, hidden models, NSFW content, and all SDK operations.

Create an API Key

  1. Go to Account Settings
  2. Navigate to API Keys section
  3. Click Add API key
  4. Copy the key immediately (shown only once)

Keep your API key secret. Never commit it to source control.

Configuration

Use application settings (recommended):

// builder.Services.AddCivitaiApi(builder.Configuration);

Example appsettings.json:

{
  "CivitaiSharp": {
    "Api": {
      "Key": "your-api-key"
    }
  }
}

For local development, use User Secrets to store the API key securely.

What Requires Authentication

Core Library:

  • Favorites
  • Hidden models
