WhatsDo for AI Agents and Developers

What WhatsDo is

WhatsDo is an action layer for AI agents. An agent sends a structured request such as “book a table for two at 7 PM”; WhatsDo checks live availability, holds the slot, takes payment and returns a confirmation. The agent gets one API instead of one integration per business.

WhatsDo is not a marketplace or a discovery layer. It executes actions at businesses that have connected their booking, point-of-sale or calendar system.

Actions an agent can take

Search — find bookable businesses and open slots near a location.
Reserve — create a reservation or appointment with a guaranteed hold.
Order and pay — complete the purchase in the same call; the business receives a confirmed, prepaid booking.
History and calendar — read past reservations and the user’s free slots.

Categories live today: restaurants and cafes, salons and beauty, wellness and spas, gyms and fitness studios, sports facilities, events.
