creditcards.best

Structured, always-current US credit-card data for agents. Use search_cards to filter, get_card for detail, estimate_rewards to rank cards for a spending profile, check_eligibility to filter by credit band, compare_cards for head-to-head, and get_apply_link for the apply URL. Every tool searches issuer-verified cards by DEFAULT; pass verified:false for the unverified stubs or verified:null for the whole corpus. Verified means sourced, not complete: values the issuer does not publish stay null, so treat a null as "the issuer does not say" and never as a zero, and never fill one in yourself. Most issuers publish no credit requirement, so check_eligibility returns far fewer cards than search_cards and excludes the unknowns rather than assuming they qualify. Rankings reflect fit, not placement. Apply links are creditcards.best tracked redirects — always hand the user those, never a raw issuer URL.
