API Endpoints

• GET / - Returns a random "no" (HTML by default, JSON with Accept header)
• GET /api/no - Explicit JSON endpoint with language detection
• GET /api/no/:lang - Get response in specific language (e.g., /api/no/no)
• GET /languages - List all available languages
• GET /health - Health check endpoint
• GET /* - Catch-all that returns "no" for any other path

Language Detection

The service automatically detects language preference through:

1. URL Parameter: ?lang=no (highest priority)
2. Accept-Language Header: Browser language preferences
3. Default Fallback: English (en)

Language family mapping is supported:

• nb, nn → no (Norwegian variants)
• sv-* → sv (Swedish variants)
• da-* → da (Danish variants)
• etc.

Adding New Languages

To add a new language, edit responses.yml:

xx:  # Language code
  name: "Language Name"
  responses:
    - "Response 1"
    - "Response 2"
    # ... more responses

Then optionally add language family mapping in app.rb if needed.
