Klook

Klook is a Hong Kong-headquartered travel and experiences booking platform for the "things to do" sector — attractions, tours and activities, theme parks, food and beverage, WiFi and SIM cards, and transportation passes. Klook publishes an Open API specification for merchants, suppliers, reservation systems and channel managers who want to distribute their inventory through Klook's website, app and partner channels. The specification is an implementation of OCTO (Open Connectivity for Tours, Activities and Attractions), the open standard for the in-destination experiences industry: the supplier implements the OCTO core endpoints (Supplier, Products, Availability, Bookings) at their own host and Klook consumes them as the reseller, with optional Capabilities negotiated through the Octo-Capabilities header. Klook additionally runs an affiliate program and a merchant portal.

Kin Score

This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Klook

Each block below is one kind of artifact we hold for Klook. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.

APIs 4

Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.

Event Specifications 1

Not every API is request/response. AsyncAPI describes the event-driven and streaming side — the webhooks and channels — so the asynchronous half of the interface is documented the same way the synchronous half is.

Security Posture 2

Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
