How to not let Curl replace space with quotes?

Question

I'm writing a bash script to launch curl requests I'm reading the input of the user and save it an variable

read theterm

Let's say the user typed :

"Hello World"

I am passing the variable to the curl request as follow :

curl 'https://someurl.com' -H ... --data '{"term":'$theterm',....}'

So while debugging my data looked like :

--data {"term" :"Hello' 'World"...}

while it was supposed to be :

--data {"term" : "Hello World"....}

Any suggestions ?
