You should use the function `call-process' as it will help with quoting: (call-process "curl" nil nil nil "-s" "https://api.mathpix.com/v3/latex" "-X" "POST" "-H" (format "app_id: %s" id) "-H" (format "app_key: %s" key) "-H" "Content-Type: application/json" "--data" "{\"src\":\"%s\", \"formats\": [\"latex_styled\"], \"format_options\": {\"latex_styled\": {\"transforms\": [\"rm_spaces\"]}}}") The data part I would format before it arrives to function `call-process' Please study the function definition with {C-h f call-process RET} -- Jean Take action in Free Software Foundation campaigns: https://www.fsf.org/campaigns In support of Richard M.
