search_cards | Filter the US credit-card dataset by product type, rewards currency (program name or kind), issuer, annual fee, foreign-transaction fee, signup-bonus value, credit band, or curated category. Searches ONLY issuer-verified cards by default, because unverified stubs carry null for most filterable fields and a null is not a zero. Set verified:false for the stubs, or verified:null to search everything params: productType, rewardsCurrencyType, rewardsCurrency, issuer, maxAnnualFee, noForeignTransactionFee, minSignupValueUsd, creditBand, category, isBusiness, verified, sort, limit |
get_card | Full detail for a single card by id (slug), including earn rates, credits, eligibility, sources and lastVerified. The apply link is our tracked redirect, not the issuer URL. params: id* |
estimate_rewards | Given an annual spending profile (USD per category, e.g. { dining: 6000, groceries: 8000, travel: 4000, other: 20000 }), estimate each card's net rewards value and rank them. Net value = rewards earned on spend + first-year signup bonus − annual fee. Statement credits are reported separately (max value if fully used), NOT folded into the headline, to avoid overstating premium 'coupon-book' cards. params: spend*, cardIds, creditBand, includeSignupBonus, limit |
check_eligibility | Given a user's credit band (and optionally income), return cards they would typically qualify for, surfacing issuer application rules (e.g. Chase 5/24) and any income floor. Only cards that publish a credit requirement can be answered; cards with no published requirement are counted in `unknownCount`, never listed as qualifying. This is a likelihood signal from published guidance, not an approval params: creditBand*, incomeUsd, cardIds |
get_apply_link | Return the apply link for a card. This is always a creditcards.best tracked redirect that records the referral and forwards to the issuer; the raw issuer URL is never returned. params: id* |
compare_cards | Side-by-side detail for two or more cards by id: fees, foreign-transaction fee, signup bonus, earn rates, credits and eligibility. Apply links are tracked redirects. params: ids* |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
