Apparently the headers in the code are not sent to the api address.

I checked the request headers in Firefox Developer Edition and saw this

Accept: text/html,application/xhtml+xml,application/xml;q=0.9,/;q=0.8
Accept-Encoding: gzip, deflate, br
Accept-Language: es-ES,es;q=0.8,en-US;q=0.5,en;q=0.3

Any hint on why the coded headers are not sent ?
