Tools: best_card lookup_merchant search_cards card rotating_calendar
best_card | 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. params: wallet*, merchant, category, valuation, on, chosen_categories |
lookup_merchant | 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. params: name* |
search_cards | 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. params: query*, issuer, limit |
card | 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. params: id* |
rotating_calendar | 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. params: card_id |
