First, obtain the URL of the RSS feed you want to convert. This URL typically ends with .rss or .xml.
Use a tool like cURL, Postman, or your preferred programming language's HTTP client to send a GET request to the API endpoint:
GET /api/rss-to-json?url=YOUR_RSS_FEED_URL
Replace YOUR_RSS_FEED_URL with the URL of the RSS feed you obtained in step 1.
