description: Split, now part of Harness Feature Management and Experimentation, is a feature flag and
  experimentation platform that enables teams to safely release features with controlled rollouts and
  measure their impact. Their developer platform provides REST APIs for managing feature flags, environments,
  segments, and workspaces, along with SDKs for evaluating feature flags across multiple languages and
  platforms.

    name: Split Admin API
    description: The Split Admin API is a REST API that enables programmatic management of workspaces
      (projects), environments, traffic types, attributes, users, groups, API keys, and change requests
      within the Split platform (now Harness Feature Management and Experimentation). The API uses resource-oriented
      URLs, returns JSON responses, and requires Admin API keys for authentication. All endpoints are
      prefixed with /internal/api/v2 on the api.split.io host.

    description: The Split Feature Flag API provides endpoints for creating, editing, and deleting feature
      flags (splits) and their definitions within specific environments. Developers can use this API to
      define treatments, configure targeting rules, set percentage-based rollouts, and manage feature
      flag lifecycles programmatically.

    name: Split Evaluator API
    description: The Split Evaluator is an HTTP service that wraps Split SDKs to provide feature flag
      evaluation via a REST API. It enables applications that cannot directly embed an SDK to request
      treatment evaluations over HTTP, making it suitable for architectures where a centralized evaluation
      service is preferred.
