# Kligo API v3

The Kligo API allows you to retrieve in real-time measurements made with connected medical devices.

Kligo embeds a WebSocket client. It can be accessed on port `63336` on the user's computer. You can register a client to this server in order to subscribe and receive the observations in real-time. To subscribe to the observations please use the following url:  `ws://localhost:63336/v3/Observation`

{% hint style="success" %}
WebSockets clients have been implemented in most languages and can easily be integrated to any project.
