Vitals™ Cloud Service
V1 Server Deprecation Notice
The V1 server (NyanCat backend) will be deprecated on June 30, 2026.
All developers must migrate to the V2 server (CrimsonLion backend) before this date. After June 30, 2026, the V1 server will no longer be available.
Please see our V1 to V2 Migration Guide for detailed instructions.
The Vitals™ Cloud Service is a cloud-based solution hosted on Amazon Web Services (AWS) that provides health analysis service using Vitals™ technologies.
There are 2 major versions of the Vitals™ Cloud Service:
Server NameServer Name | Server IDServer ID | DescriptionDescription |
|---|---|---|
| NyanCat | ServerId.AwsProdEnterprise | V1 backend. Deprecated - Will be removed on June 30, 2026. |
| CrimsonLion | ServerId.Schema2Prod | V2 backend that includes all the vital signs supported in NyanCat, and additional vital signs (e.g., physical wellness, mental wellness, etc.). Beta ends June 30, 2026. |
To access the Vitals™ Cloud Service, you will need an API Key and a User ID. The API Key serves as the credential for accessing the Vitals™ Cloud Service, while the User ID specifies the subscription plan for the service. The set of vital signs obtained from a scan varies depending on the licensed subscription plan, with each plan offering a unique set of vital signs. If you do not have these credentials yet, please contact us to obtain them.
TIP
For more details, please refer to the Interpreting Results page which provides the full list of vital signs supported by the two Vitals™ Cloud Service versions.
To use the V2 server (CrimsonLion): Simply set the precisionMode property in your configuration. The SDK will automatically use the V2 server when precision mode is enabled. See our Migration Guide for details.
About CrimsonLion backend (V2)
The CrimsonLion (V2 backend) represents the next generation of our backend services. It is designed to offer more comprehensive health analysis and enhanced performance.
Beta Status: Currently in beta stage, ending on June 30, 2026, at which point it will become the stable, production-ready backend.
We strongly encourage all developers to migrate from NyanCat (V1) to CrimsonLion (V2) before the deprecation date. See our Migration Guide for details.
How It Works?
Vitals™ SDK takes care of the communications between the client and the Vitals™ Cloud Service for you. It accomplishes this by gathering necessary data, such as the signals extracted during the 30-second scan and the user information (e.g., age, gender, etc.) you provided to our SDK. On the other hand, Vitals™ SDK also parses responses from the cloud server and returns a Health result object for the app to display or process. You do not need to handle communications with the Vitals™ Cloud Service yourself.
TIP
Please refer to the Privacy and Security page for more details on how we handle the data securely.
