}The card-selection oracle for agents: which of your credit cards should pay here? Answers come from RightCard's bank-published, two-source-verified reward data — the same data the RightCard iOS app uses.
valuation: "points" for conservative travel values.Hosted (stateless Streamable HTTP):
Local (stdio, nothing leaves your machine except a read of the public catalog):
Claude Desktop / Claude Code / Cursor config:
Try: "I have the Amex Gold, Freedom Flex and Citi Double Cash. Which one at Costco?"
src/engine.ts is a port of the iOS app's Swift engine. fixtures/engine_golden.json holds
3,100+ answers produced by the Swift code over the real catalog and merchant directory;
npm test fails if the port disagrees on any of them. Offers (a user's personal bank offers)
are deliberately not part of this server — they live on the phone.

Best card for a store or category
Which of the given cards earns the most at a store (merchant) or for a spend category, today. Returns the card, the honest rate, why, and caveats (merchant-code traps, activation, ties). Base rates + rotating bonuses + built-in card benefits only; a user's personal bank offers live on their phone and are not consulted here.
onwallet必填categorymerchantvaluationchosen_categoriesHow a store is coded
The store's reward category as RightCard's directory files it, its merchant type, and the merchant-code caveat when a category bonus usually will not post there (superstores like Walmart/Target, warehouse clubs like Costco/Sam's). Same ranking the app uses.
name必填Find card ids
Search RightCard's catalog by card or issuer name to get the ids to pass into best_card. Verified cards first; unverified cards are flagged, never hidden.
limitquery必填issuerA card's verified rates
Everything RightCard knows about one card: rates by category, base rate, currency, annual fee, verification status, live rotating windows, and the choose-your-category spec if it has one.
id必填Rotating 5% windows
Live and upcoming rotating-category windows (Freedom Flex, Discover it, Citi Dividend…) and permanent merchant benefits, from the same verified data as the app. Optionally filter by card id.
