DESCRIPTION

       This Catmandu::Fix provides a method to fetch JSON data from an URL. The response is added as new item or
       to a field of the current item.

OPTIONS

       The first argument must be an URL, an URL template, or a field where to take an URL or URL template from.
       Additional options include:

       path
           Field to store result JSON in. If not given or set to the empty string, the whole item is replaced by
           the fetched JSON response. If the first argument is a field, the same field is used as "path" by
           default.

       vars
           Field to get URL template variables, URL query parameters or an URL path expression from. This option
           is required if the first argument is an URL template.

       The fix function also supports options "dry", "cache", "timeout", "agent", "proxy", and "wait" as
       documented in Catmandu::Importer::getJSON.  Options "client", "headers", and "warn" are not supported.
