Know your
ceiling.

1. In Shortcuts, create a shortcut named Check Pokémon Deal.
2. Open its Details, enable Show in Share Sheet, then tap Done. Set accepted input types to URLs and Text.
3. Add Get URLs from Input, using Shortcut Input.
4. Add Get Item from List, set to First Item from the URLs.
5. Add URL Encode, set to Encode, using that first URL.
6. Add Replace Text: replace the literal + with %2B in the encoded result (Regular Expression off). This preserves plus signs if your iOS version leaves them unescaped.
7. Add a Text action containing https://tuanwoodruff.com/ebay?listing=, followed immediately by the output variable from Replace Text.
8. Add Open URLs using that Text output. Encode only the original listing URL, once.
9. In eBay, open a listing → Share → Check Pokémon Deal. Sign in if needed, confirm the card, then inspect evidence and calculate.

If no URL is shared, paste the eBay link directly into this page. This is a manual Shortcut setup, not an installed share extension.
