}🟢search_card_offers(issuer, merchant, card, expiring_within_days, popular_only, ...)
Card-linked merchant offers (Amex Offers, Chase Offers) that are live today, as seen by MaxWorth browser-extension users: merchant, the deal, fine print, latest expiry seen, and which cards it has appeared on. Filter by issuer, merchant, card, expiry window or popularity; with no filters it returns an overview. Offers are targeted per account: a card listed means several users saw the offer on that card, not that every cardholder has it.
