# Check Berlin City Tour ticket availability for a date

Automatically check Berlin City Tour ticket availability for a date on berlin-city-tour.de. Reads the Berlin City Tour shop for one calendar date and returns the bookable timeslots, the per-guest-category prices, and the remaining capacity. The Hop-on Hop-off Classic tour is sold as a day ticket, so a bookable date has a single open timeslot covering the whole day rather than departure times. When the date is not on sale it returns available false with the reason the shop gave and the other dates on sale around it, so the caller can offer an alternative instead of guessing. The offer_hash it returns identifies the date, the slots and the prices it saw; pass it to add_to_cart, which refuses if the shop has changed since.
