compare_cards_for_purchase
shallowca.creditgps/canadian-credit · Verify this server
Use this when someone asks which card to put a purchase on. Returns two answers for the amount given: the card that reports the least utilization impact, the card that is cheapest to carry, and the trade-off when those differ, because the card the bureaus notice least is often not the card with the lowest rate. Calculates scenarios from supplied figures; does not make payments, change accounts, fetch external data, or retain tool inputs.
