best_card Best card for a store or category ~226
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.
| Name | Type | Req | Description |
|---|---|---|---|
| category | string | – | Spend category when there is no specific store. |
| chosen_categories | object | – | For choose-your-category cards (Citi Custom Cash, BofA Customized, Venmo): card id → the categories the person set. |
| merchant | string | – | Store name, e.g. 'Costco', 'Whole Foods', 'Uber'. Use this OR category. |
| on | string | – | Date (YYYY-MM-DD, UTC) for rotating windows; defaults to today. |
| valuation | string | – | 'cash' counts every point at 1¢ (default). 'points' values points per program at conservative travel values. |
| wallet | array | yes | Card ids the person holds (from search_cards). |
No output schema declared.
No examples provided.
card A card's verified rates ~52
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.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | yes | – |
No output schema declared.
No examples provided.
lookup_merchant How a store is coded ~70
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 | Type | Req | Description |
|---|---|---|---|
| name | string | yes | – |
No output schema declared.
No examples provided.
rotating_calendar Rotating 5% windows ~53
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.
| Name | Type | Req | Description |
|---|---|---|---|
| card_id | string | – | – |
No output schema declared.
No examples provided.
search_cards Find card ids ~62
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.
