What this server can do
6 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.
check_eligibility(cardIds, incomeUsd, creditBand)- 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 guarantee. Required: creditBand.
compare_cards(ids)- 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. Required: ids.
estimate_rewards(limit, spend, cardIds, creditBand, includeSignupBonus)- 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. Returns a per-category breakdown and the assumptions used. All card facts come from the verified dataset; only point valuation is modeled. Required: spend.
get_apply_link(id)- 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. Required: id.
get_card(id)- 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. Required: id.
search_cards(sort, limit, issuer, category, verified, creditBand, isBusiness, productType, maxAnnualFee, rewardsCurrency, minSignupValueUsd, rewardsCurrencyType, noForeignTransactionFee)- 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 knowingly. Returns at most 25 summaries unless you raise `limit`; `total` is the full match count and `truncated` says whether you are seeing all of it. Rankings reflect fit, not placement.

Signals
These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.
