A dot represents the entire input, but formatted with indents:
curl ipinfo.io | jq ‘.'
.[] returns each element of the array, one at a time,
curl ipinfo.io | jq ‘.[]'

curl ipinfo.io | jq -r .city
NOTE: jq receives a file piped in, as specified by the pipe character . To return the response in a variable within a Bash script:
CITY=$( curl ipinfo.io | jq -r .city )
