curl -sS --fail-with-body \
  -o rotated.pdf \
  -H "Authorization: Bearer $OHMYWRAP_KEY" \
  -F "file=@scan.pdf" \
  -F 'options={"rotation":-90,"pages":["2-3"]}' \

Options

Options accepted inside the options JSON object
Option	Type	Default	What it does

pages	string[]	all pages	Page selection: "2", "2-4", "odd", "even", "3-", "-2". Ranges are clamped to the document.
