The Terra Fitness and Health API

This company provides an API designed to safeguard privacy that allows apps access fitness and health data such as daily activity and biomarkers through HTTP requests.

Its goal is to enable non-health-tech companies to use data derived from wearable devices to create better products, such as Spotify using your heart rate to tailor song recommendations or Netflix suggesting movies based on stress levels.


Terra has developed an API that unifies thousands of wearable devices and services, and its goal is to aid developers in creating products for users that are easy to use across devices and work seamlessly for users. This enables apps to tailor experiences specifically to users while increasing engagement levels; track progress of users; measure user health status etc.

The API enables fitness app developers to access data from all connected wearables, allowing them to customize the user experience and track progress. It provides information regarding sleep cycles, stress levels, nutrition intake and even features a dashboard which gathers all of this data in one convenient place – all free for iOS and Android users alike!

Kyriakos Eleftheriou, the founder of Terra, discussed his company’s vision for the future of fitness and health in an interview. He noted the importance of making fitness data as accessible as possible for use by music companies to recommend songs more accurately while Netflix could use your heart rate measurement as stress indicator to recommend movies more appropriately.

Eleftheriou announced that Terra has already attracted around 100 developers to its platform and expects this number to continue rising as demand for Terra’s services increase. Furthermore, Eleftheriou stated his intent of expanding his team from its current four members (co-founders and two other engineers) up to seven over time.

He also discussed how the company plans to connect its platform with non-health tech companies in order to unlock additional uses of fitness data, for instance using Spotify to make more accurate song recommendations using user’s heart rates. These connections would require user permission and would not store in their system in order to preserve privacy.

The Terra fitness and health API aims to address data siloing. Its platform-agnostic API enables developers to access wearable and sensor data using HTTP requests; its underlying architecture relies on REST principles with JSON-encoded request bodies, standard HTTP response codes, authentication methods, verb support, etc.


The Fitness API connects fitness apps and hardware with data such as daily activity and biomarkers. Organized using REST, this API accepts form-encoded request bodies, returns JSON-encoded responses and uses standard HTTP response codes, authentication verbs and response codes for real-time access to fitness- and health-related data.

Terra recently secured a $2.8 million round from General Catalyst, Samsung Next and NEXT VENTURES; with this funding the team can increase the number of developers accessing Terra’s APIs and also develop one to provide real-time access to fitness and health related data.

Fitness apps have become an invaluable way to support healthy habits and track them across multiple devices, but aggregating this data is often challenging. Terra is an innovative new platform which solves this issue by connecting fitness apps directly with fitness hardware and software, as well as making it simple for third-party developers to develop apps with access and analysis features for fitness and health data.

Even though there have been concerns regarding privacy and security, the company has made every attempt to safeguard user data. They have implemented a strict policy for how their customers use any personal information they give. Furthermore, none of this personal data is stored on any servers owned by the company.

Hackers need more difficulty accessing sensitive information like health, fitness and nutrition data; updating systems is also vital to protecting users against malicious software attacks.

As part of their platform, this app offers consumers an additional means of tracking their health: they can see their progress, set goals, and receive coaching – perfect for both Android and iOS phones. Making the most out of exercise programs.

Kyriakos Eleftheriou, co-founder and CEO of Terra, explained in an interview with TechCrunch that his aim is to become the “Plaid for fitness data.” Rather than creating an entirely new ecosystem, Terra seeks to connect existing ones so third-party services may use this connectivity for personalized experiences; such as music players linking playlists to the user’s heart rate to play music at more conducive tempo when exercising.


Terra’s platform was designed with user privacy in mind; it does not store or analyze any of the data users upload, instead only using aggregated and anonymized information to improve service delivery. Terra has earned a strong reputation among tech developers; over 500 developers utilize Terra APIs. Furthermore, users have access to an app where they can manage and view their own data.

Kyriakos Eleftheriou, co-founder of Terra and recent graduate of Y Combinator, is an ex-special forces commando turned entrepreneur. Terra aims to address data siloing by connecting thousands of devices through one connection point.

Terra, an early-stage YC company, is developing an open API that will integrate wearable devices from various manufacturers – Apple, Garmin, Samsung, Peloton and Polar among them – with real-time tracking and data visualization features, third-party developer applications and services, etc. The API features real-time tracking as well as real-time visualization.

This company provides both a free version of its API, with limited integrations with certain wearable devices, and a paid plan supporting unlimited integrations and more features. Furthermore, in addition to their API they also offer an online dashboard to monitor user activity as part of REST platform that accepts form-encoded request bodies, returns JSON-encoded responses, as well as standard HTTP response codes, authentication methods, and verbs.

Terra offers more than an API: it also offers a web dashboard which showcases user activity and data from popular fitness and health devices on the market. Its simple user interface enables customization so only desired data will appear; plus its graphical representations help track progress toward your goals while motivating you towards meeting them!

Eleftheriou recently told TechCrunch that her company plans to expand its team in order to support its continued growth, with particular attention paid to expanding integration points with companies providing APIs, SDKs and Bluetooth-enabled health wearables.

Terra is an application programming interface (API) provider that enables developers to connect fitness and health devices and apps. Their API provides access to wearable data from devices like Garmin, Fitbit, Apple, Google Polar Eight Sleep Oura. In 2020 Terra was founded in Maidenhead UK.

APIs provided by this company allow developers to connect their apps with fitness and wellness devices, and aggregate and analyze fitness data. With these APIs, developers can personalize user experiences, facilitate engagement, monitor results, make informed decisions regarding products/services offered and even create new fitness-related offerings using APIs from this company.

Terra, a recent graduate of Y Combinator, recently closed a $2.8 million funding round from General Catalyst, Samsung Next and NEXT VENTURES. The funds will be used to expand Terra’s team and develop additional integration points for its APIs – including adding more engineers to accommodate growing demand for fitness and health data.

Eleftheriou’s aim is to build an open source platform that will support various technologies. His startup will earn money by allowing companies like Spotify to read your heart rate and create more accurate music recommendations – without accessing or storing any personal data from users.

Terra API stands out among many similar services by offering several unique features. This includes: a widget enabling users to log in and sync up various devices; an SDK for developers to create new products and services; as well as real-time health information using RESTful technology that accepts form-encoded requests bodies with JSON encoded responses that use standard HTTP response codes, authentication and verbs.
