Use cases
What people buildwith card prices.
Each idea below lists the endpoints it uses, so you can size the work before writing code. The free plan is enough to build a prototype of any of them.
Storefront repricing
Pull your inventory in batches of up to 500 cards, apply your own margin by condition, and update your listings on a schedule. Market prices refresh every 6 hours, so a nightly job always reads fresh numbers.
Buylists and trade-in quotes
Quote what you will pay for a card at the counter by comparing recent sold prices with the cheapest live listing.
Collection trackers
Store card_id and sku_id for what each user owns, then refresh values in bulk. History gives you the chart for each card.
Deck cost calculators
Price a full deck list in one request, in the condition the player wants, and show the cheapest listing next to the market price.
Price alerts
Watch the cards your users care about and notify them when the market price or the cheapest listing crosses their target.
Market dashboards
Chart a set or a chase card over 30 days to a year with daily and weekly sold history, including quantity sold.
Card scanners
After your scanner reads a card's name and set, search for it and show its value in every condition.
AI agents that know prices
Connect an agent through the MCP server so it can look up cards, compare conditions and read price history while it works.
