Everything you need before your first API call.

## 🔑 Basics

The OkupAI API gives you programmatic access to your booking data. Before using the endpoints, read these two pages:

* [**Authentication**](/okupai-api/basics/authentication.md) — how to authenticate every request with your API key
* [**Pagination**](/okupai-api/basics/pagination.md) — how list responses are paginated

{% hint style="info" %}
API access is a separate subscription add-on. Contact us at <office@okup.ai> to get your API key.
