  title: Opik REST MCP OAuth API
  description: "The Opik REST API is currently in beta and subject to change. If you have any questions or feedback about the APIs, please reach out on GitHub: https://github.com/comet-ml/opik.\n\nAll of the methods listed in this documentation are used by either the SDK or the UI to interact with the Opik server. As a result,\nthe methods have been optimized for these use-cases in mind. If you are looking for a method that is not listed above, please create\nand issue on GitHub or raise a PR!\n\nOpik includes two main deployment options that results in slightly different API usage:\n\n- **Self-hosted Opik instance:** You will simply need to specify the URL as `http://localhost:5173/api/<endpoint_path>` or similar. This is the default option for the docs.\n- **Opik Cloud:** You will need to specify the Opik API Key and Opik Workspace in the header. The format of the header should be:\n\n  ```\n  {\n    \"Comet-Workspace\": \"your-workspace-name\",\n    \"authorization\": \"your-api-key\"\n  }\n  ```\n\n  The full payload would therefore look like:\n  \n  ```\n  curl -X GET 'https://www.comet.com/opik/api/v1/private/projects' \\\n  -H 'Accept: application/json' \\\n  -H 'Comet-Workspace: <your-workspace-name>' \\\n  -H 'authorization: <your-api-key>'\n  ```\n\n  Do take note here that the authorization header value does not include the `Bearer ` prefix. To switch to using the Opik Cloud in the documentation, you can\n  click on the edit button displayed when hovering over the `Base URL` displayed on the right hand side of the docs.\n"
