How do I loop through this routine X number of times where the text on line 7, and the filename on line 13 change every time? Is there a sane way to make a loop of this?

curl -X 'POST' \                                                                                                                                                  
  'https://api.url.foo/v1/foo/someID' \
  --header 'accept: audio/mpeg' \
  --header 'api-key: somekey' \
  --header 'Content-Type: application/json' \
  --data '{
     "text": "This text will change every time.",
     "model_id": "id_v1",
     "voice_settings": {
     "stability": 0.5,
     "similarity_boost": 0.5
    }
  }' --output "this_title_will_change.mp3"

first

curl -X 'POST' \

Just so I understand you mean something like this even though it is manual. Is there a reason you want to do this with curl verses a programming language?
