  title: CircleCI REST API v2 Context API
  description: The CircleCI REST API v2 provides programmatic access to CircleCI services for managing pipelines, projects, workflows, jobs, and users. Developers can trigger pipelines, retrieve build status, manage contexts and environment variables, and access usage reports. The API uses token-based authentication via a Circle-Token header and returns JSON responses. It supports operations for project configuration, workflow management, artifact retrieval, and insights into build performance.
