Terra API
Unified API that connects apps to wearables, health apps, sensors and lab data in one standard format.
Terra API is a unified health and fitness data API. Terra API lets developers connect an app to more than 500 wearables, health apps, sensors and lab providers through one integration and receive standardised activity, sleep, body and nutrition data. Terra API is used by adding its sign-in widget and reading data through webhooks, SDKs or an MCP server.
Best for Developers of health, fitness and performance products who want wearable and biomarker data from many providers without maintaining each integration themselves.

What is Terra API?
Terra API is a developer service that links health and fitness applications to wearables, health apps, medical devices, sensors and blood-testing providers through a single integration. Instead of building a separate connection for each source, a developer calls one API and receives activity, sleep, body and nutrition data in a common schema from more than 500 providers, among them Oura, Garmin, WHOOP, Fitbit, Strava and Apple Health. Terra manages OAuth, token refresh and an embeddable sign-in widget that can carry the host app's branding. Data can be pushed to webhooks, SQL databases, cloud storage or queues. Add-ons include health scores, rewards and streaks, a Graph API, lab report parsing, planned workouts generated from a prompt and sent to devices, real-time streaming, and an MCP server called AI Interface that lets an agent read a user's data. A Teams API covers athlete performance platforms.
