# Health Health Check is a method to verify the availability and operational status of the TEOS API. It confirms whether the API is online and responsive, and can also validate the provided API key or authorization token. This endpoint performs no business logic and returns an empty successful response if the service is healthy. It is commonly used for automated monitoring, pre-flight connectivity checks, or credential validation before sending other API requests. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
