When trying to access the API for the first time using json I get: XMLHttpRequest cannot load https://api.wunderground.com/api/bdb4.... Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://www.negoagro.com' is therefore not allowed access. The response had HTTP status code 501.
