# What is Terra API?

Terra is a **unified API for health and wearable data**.

We make it simple for developers to connect their applications to a vast ecosystem of fitness trackers, smartwatches, and medical devices without building or maintaining individual integrations.

## Why Terra?

### The problem we solve

Accessing health data is complex. Each device and platform (like Garmin, Fitbit, Apple Health, Oura) has its own API and data formats.

### Our solution 

One unified API to access standardised data from hundreds of sources. We handle the complexity of:

* Integrating with numerous providers.
* Normalising diverse data formats.
* Managing different authentication methods.

Essentially, we handle the **infrastructure** so you can focus on **building the future of heath**.
