Remove All Origin Pull Request Labels via the API

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

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.

The call succeeds when the pull already has no labels. An unknown or unreachable pull returns 404. A 404 never distinguishes a missing pull from one your installation cannot reach. Pull request number is a JSON string. The successful response body is empty.

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