You could use command substitution:
VAR=$(curl -H "Content-Type: application/json" -X POST -d '{"hash":"$restearterHash"}' {$host}ApiController/jsonRestarter/ | python -m json.tool)
echo "${VAR}"

Welcome to StackOverflow, and thank you for using proper code formatting and providing a link to authoritative documentation! That said, note the section "Answer Well-Asked Questions" in How to Answer, particularly the following bullet point regarding questions which "have already been asked and answered many times before".
You can store the output of a command like this: var=`command`,
so this should work fine for you:
json=`curl -H "Content-Type: application/json" -X POST -d '{"hash":"$restearterHash"}' {$host}ApiController/jsonRestarter/ | python -m json.tool`

var=$(somecommand) is the modern syntax (present in the 1991 POSIX sh standard, so present in any standard-compliant shell written or updated in more than 25 years). $() nests better than backticks, and backslash literals contained therein have less surprising behavior.Charles Duffy
Also, see How to Answer in the help center, particularly the section "Answer Well-Asked Questions", particularly the section requesting that one not answer questions that have been asked and answered many times before.
json.tooldoesn't change the output into JSON -- if json.tool accepts it as input, it's already JSON to start with.jqfor that. We already have lots of questions and answers in the knowledgebase describing how to do so; please search before you ask.
