{"version":"1.0","type":"rich","title":"cURL tips","description":"This example demonstrates a practical cURL command for creating a user account via a REST API. It shows a POST request to the `/signup` endpoint, explicitly setting both `Accept` and `Content-Type` headers to `application/json`. The request body is piped from standard input using the `-d @-` flag, with the JSON payload containing an email and birthday. The example relies on the cURL command-line tool and the HTTP protocol, with no JavaScript libraries or rendering involved. It highlights the correct syntax for sending JSON data from a terminal without needing a separate file.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-6008348?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
