You have basically two options:
1. Knowing the string syntax rules, you can interpret the escapes in
your head, removing the double quotes at start and end and replacing
each \" → " and \\ → \.
2. Or you can use an Emacs function that accepts a string and causes
its interpreted contents to be inserted into some buffer, e.g.
(message "…") or (insert "…").
$ emacs -Q
(insert "curl -s https://api.mathpix.com/v3/latex -X POST -H \"app_id:
%s\" -H \"app_key: %s\" -H \"Content-Type: application/json\" --data
\"{\\\"src\\\":\\\"%s\\\",\\\"formats\\\":[\\\"latex_styled\\\"],\\\"format_options\\\":{\\\"latex_styled\\\":{\\\"transforms\\\":
[\\\"rm_spaces\\\"]}}}\"")
Either way, you get:
curl -s https://api.mathpix.com/v3/latex -X POST -H "app_id: %s" -H
"app_key: %s" -H "Content-Type: application/json" --data
"{\"src\":\"%s\",\"formats\":[\"latex_styled\"],\"format_options\":{\"latex_styled\":{\"transforms\":
[\"rm_spaces\"]}}}"
Before you can try this in your terminal, you’ll need to substitute
the %s placeholders.
