Hints

With curl you can get the content of the file from the url:

$ curl https://((DOMAIN))/assets/superhero/all.json
<...>
$

jq is a command-line utility that can slice, filter, and transform the components of a JSON file

$cat fruit.json
{
  "name": "apple",
  "color": "green",
  "price": 1.0
}
$jq '.color' fruit.json
"green"
$

grep is a command-line utility for searching plain-text data sets for lines that match a regular expression.

$cat fruit.json
{
  "name": "apple",
  "color": "green",
  "price": 1.0
}
$cat fruit.json | grep color
  "color": "green",
$

You may need to use pipes (|) and the logical operator &&.

You have to use Man or Google to know more about commands flags, in order to solve this exercise! Google and Man will be your friends!
