Find the lowest-priced eSIM data plan for a destination — for "what's the cheapest", "budget option", "cheapest SIM / data plan for X". Pass days (trip length) to rank by what the traveller actually pays for the whole trip: unlimited plans are priced per day with a multi-day discount, fixed-data plans by their sticker price, and plans that expire before the trip ends are dropped. Without days it ranks by daily rate. Returns up to 3 options with variant_id for create_checkout.
