Discovery versus live pricing
The cached discovery tools are optimized for speed and broad exploration. Once you have a candidate offer, switch to live pricing to confirm the fare and obtain atrip_item_token.
Tokens and IDs
offer_tokenidentifies a candidate itinerary returned by discovery.trip_item_tokenidentifies a price-checked itinerary that can be added to a trip.trip_ididentifies the mutable trip/cart used for quoting, payment, and booking.
Hosted checkout
Jinko owns the payment surface. Your agent prepares the trip, sends the user tocheckout_url, and then confirms payment to trigger booking.
