By TANSU CABACI

Overview

Cardwell helps you compare a focused selection of U.S. credit cards based on what matters to you: cash back, travel rewards, 0% intro APR, or business needs. Answer a few simple questions to see a Best Match and Second Choice, with clear reasons and links to issuer information. Cardwell does not collect sensitive financial information or guarantee approval.

Tools

get_card_application_link

ChatGPT

Always use when the user asks where or how to apply, requests an application link, or wants to continue with a Cardwell card. Accepts a Cardwell slug, catalog ID, legacy ID, or exact card name. Returns applicationUrl, linkType, officialUrl, disclosure, and freshness date. A referral link is returned when available; otherwise applicationUrl falls back to the official issuer URL. Referral availability never affects rankings.

get_card_details

ChatGPT

Get stored facts, applicationUrl, linkType, disclosure, official issuer URL, and freshness date for one Cardwell card. Include the application link and disclosure when presenting the card; officialUrl is for checking terms. Accepts a Cardwell slug, catalog ID, legacy ID, or exact card name.

list_cards

ChatGPT

List the fixed Cardwell catalog, optionally filtered by personal/business type and goal.

recommend_cards

ChatGPT

Return Best Match and Second Choice from complete or partial broad preferences. Use preferences already supplied and do not restart if an answer is skipped or expires. Explain tradeoffSummary when present so conflicting preferences are handled transparently. Rankings use card features and user preferences; referral relationships never influence the two ranked results. Every returned card includes applicationUrl, linkType, disclosure and officialUrl. Show the application link and disclosure with each presented result, without waiting for the user to ask where to apply; preserve applicationUrl exactly. When referralAlternative is present, also show it as a separately labeled Additional suitable referral option; it must not replace or reorder the two ranked results. Respect requests for official-only links or no referral options. Cardwell never predicts approval.
