Flagsmith Flags API is one of 9 APIs that [flagsmith](https://apis.io/providers/flagsmith/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Edge, Feature Flags, Flags, Remote Config, and SDK. The published artifact set on APIs.io includes API documentation and an OpenAPI specification.

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.
