# API Reference — Introduction

> How InsightAI's APIs are organized

InsightAI's APIs are split by product:

<CardGroup cols={2}>
  <Card title="Device Intelligence APIs" icon="mobile-screen" href="/api-reference/endpoint/di/ingest_telemetry">
    Telemetry ingest, alerts, and device lookup — everything the SDK and your backend integrate against.
  </Card>

  <Card title="Authentication" icon="key" href="/api-reference/authentication">
    Key types, HMAC signing, and how request/response signing works.
  </Card>
</CardGroup>

Every endpoint uses the same base URL and authentication scheme — see [Authentication](/api-reference/authentication) before making your first call.
