Capabilities

Tools 4

check_availability

Booked nights and the open date ranges a stay can actually be booked in, with minimum-stay rules applied. bookableFrom is the first check-in a request made now may ask for (later than today when the host requires notice before check-in). bookableUntil is the first night the host's booking window has not opened yet (24 months from today when the host has not set one); nights after it are not open rather than taken. The listing's maxNights is the longest stay a quote accepts. Defaults to the next 90 days; at most 365 days per call. Ranges are check-in inclusive, check-out exclusive.

Discovered
find_property

Look up a vacation rental by its RentalCal booking site, or by the page on the host's own website where their RentalCal booking widget is installed. Accepts a site address such as beach-house.rentalcal.com, a full URL, the bare site name, or the host's own domain. Returns the listing: description, location, capacity, amenities, house rules, photos, nightly pricing, cancellation policy, payment schedule, damage deposit, the host's FAQ, and the property id. When one website hosts several properties, returns those candidates instead.

Discovered
get_property

The full listing for a property id: description, location, check-in and check-out times, capacity, pets, amenities, house rules, photos, nightly pricing and fees, cancellation policy, payment schedule, damage deposit, and the host's FAQ. Amounts are integer cents in the property's currency.

Discovered
get_quote

The exact price of a stay: nightly rates, discounts, cleaning and other fees, taxes and total, in integer cents, plus any refundable damage deposit the host requires and whether it is held at booking. Returns a bookingUrl that opens the host's booking page with these dates and guests filled in, where the traveller completes the booking. If the stay is not allowed (dates taken, below the minimum stay, too many guests) the reason is returned instead.
