How to build card apps with live prices.
Step-by-step guides for the apps people build most: card scanners, collection trackers, store repricing and price bots. Each one lists the endpoints it uses and how many requests it needs, so you can pick a plan before you write code.

How to reprice your card store's inventory automatically every day
Match your stock to cards once, look up current prices in bulk each night, apply your own margins by condition, and update your online store or price tags. Works for Shopify, other carts and in-store stock.
