What you can build with CardAPI
Each guide lists the fields and endpoints it needs, the plan that returns them, how you may display and cache the data, and code that runs on your own key.
Use cases
- Build a credit card comparison siteStarter plan and aboveA comparison site lists cards, filters them and shows two or three side by side. CardAPI gives you the card list and every field the table needs, for the US and Canada; you own the design, the ranking and the editorial.
- Build a rewards optimizerStarter plan and aboveA rewards optimizer answers one question: of the cards in this wallet, which one earns most here? It needs every reward rate of each card, matched on canonical categories, and a value per point to compare points, miles and cash back.
- Build a travel rewards appPro plan and aboveA travel app turns a wallet into trips: which programmes the user's points move to, which credits and perks the cards carry, and which card to pay with abroad.
- Card data for bloggers, newsletters and creatorsPro plan and aboveCard content goes stale the day an issuer changes an offer. CardAPI tells you what changed and when, so a review, a newsletter or a best-cards page shows today's numbers.
