man curl:

       -v, --verbose
              Makes the fetching more  verbose/talkative.  Mostly  useful  for
              debugging.  A line starting with '>' means "header data" sent by
              curl, '<' means "header data" received by curl that is hidden in
              normal cases, and a line starting with '*' means additional info
              provided by curl.

              Note that if you only want  HTTP  headers  in  the  output,  -i,
              --include might be the option you're looking for.

              If  you think this option still doesn't give you enough details,
              consider using --trace or --trace-ascii instead.

              This option overrides previous uses of --trace-ascii or --trace.

              Use -s, --silent to make curl quiet.
