# Introduction

The Raa Labs Time Series API provides endpoints to access time series measurements, metadata, and aggregated statistics. This reference outlines each endpoint and how to use them, including authentication requirements, query parameters, and example usage.

You are reading the documentation for API version `2026-09-10`. If you are upgrading from version `2025-10-31` you can find a migration guide and key updates [here](/getting-started/changelog/versions.md#2026-09-10).

We recommend to start by reading through the [Authentication](/getting-started/authentication.md) section, and then head over to the [Quickstart](/getting-started/quickstart.md) guide and [Best Practices](/getting-started/best-practices.md).
