Remove an Origin Pull Request Label via the API

Remove one label from a pull request with DELETE https://api.cursor.com/v1/origin/repos/{ownerSlug}/{repoName}/pulls/{pullNumber}/labels/{labelName}. Official reference: Origin API → Remove Pull Request Label (OpenAPI OriginService_RemovePullRequestLabel).

Origin is in Early Beta and subject to change. Authenticate with an installation access token (oit_…) or a user access token that carries repository:pull_requests:write. Availability: Early Beta per the API overview.

A label that is not assigned to the pull returns 404, as does an unknown or unreachable pull. A 404 never distinguishes a missing resource from one your installation cannot reach. Pull request number is a JSON string.

Cost: 5 points against the principal budget (ordinary write).

Response

200 returns labels remaining on the pull request, ordered by name. Each entry carries id, name, color, and description.
