API Key Authentication

All API requests require an X-API-Key header with your API key. 
curl -X GET "https://api.fieldfunded.com/v1/sports" \
  -H "X-API-Key: YOUR_API_KEY"
Never expose your API key in client-side code or public repositories. Always use server-side requests or environment variables.
