Look up a copied number with an iPhone shortcut

Build a shortcut in the Shortcuts app as below, copy a number or message text, then run the shortcut to look it up on Denwa. A number opens its page; text without a number opens the SMS scam checker.

  1. In the new shortcut's details, turn on "Show in Share Sheet" and set what happens when there is no input to "Get Clipboard"
  2. Add the "URL Encode" action and set its input to "Shortcut Input"
  3. Add a "Text" action, type https://denwa.click/en/search/?text=, then add "URL Encoded Text" right after it
  4. Add the "Open URLs" action and save
