PokEbay Lookup Tool is a free Chrome extension developed by shutupflanders. It falls under the category of Browsers and is categorized as an Add-ons & Tools subcategory. This tool allows you to easily compare your Pokémon Trading Card Game (TCG) collection with the current eBay listings page.

When you visit eBay listings pages under the category "Pokemon Cards," the extension automatically scans each listing. It extracts the name and number of each card, if available, and sends this information to a predefined self-hosted API. The API is hosted on tcgcollector.com, a website where you can keep track of your Pokémon TCG Collection.

The purpose of this tool is to check if the cards listed on eBay are already in your collection. If a card is found, the tool replaces the listing item's title with green text. On the other hand, if a card is not found in your collection, the tool replaces the title with red text. This feature helps you easily identify which cards you still need to complete your collection and allows you to do so quickly.
