      The Flagsmith Flags API is the public-facing REST API that client-side and server-side SDKs use to retrieve
      feature flag values and remote configuration for environments and users. It uses a non-secret Environment Key for
      authentication and is designed to be fast, scalable, and publicly accessible. The Edge API endpoint at
      edge.api.flagsmith.com serves requests from AWS Lambda functions running in data centers near the client,
      providing low-latency global access to flag evaluations.

      The Flagsmith Admin API allows developers to programmatically manage all aspects of their Flagsmith projects.
      Anything that can be done through the Flagsmith dashboard can also be accomplished via this API, including
      creating, updating, and deleting projects, environments, feature flags, segments, and users. It uses a secret
      Organisation API Token for authentication and provides a Swagger interface at api.flagsmith.com/api/v1/docs for
      interactive exploration.
