CircleCI Self-Hosted Runner API

The CircleCI Self-Hosted Runner API enables management and execution of jobs on self-hosted runner infrastructure. It provides endpoints for listing available runners, managing runner tasks, and querying resource classes. The API is hosted separately from the main CircleCI API at runner.circleci.com and supports multiple authentication methods depending on the endpoint. Developers can use this API to integrate self-hosted runner management into their infrastructure automation workflows.
