The HTML to JSON API is a tool that converts HTML code to JSON format. This can be useful for developers who want to extract data from HTML documents and use it in JSON-based applications. The API takes an HTML document as input and returns a JSON object that contains the same information in a structured format.

This endpoint takes the information (string) as input, and provides the JWT-encoded result (string) as output. The output also includes a copy of the input, and a « status » value. Status is « Ok » or « Error: … ».
