List Origin Pull Request Labels via the API

List every label assigned to a pull request with GET https://api.cursor.com/v1/origin/repos/{ownerSlug}/{repoName}/pulls/{pullNumber}/labels. Official reference: Origin API → List Pull Request Labels (OpenAPI OriginService_ListPullRequestLabels).

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:read. Availability: Early Beta per the API overview.

The response is the full assigned list ordered by name. There are no pagination parameters. A pull request can have at most 100 labels. Pull request number is a JSON string (protobuf 64-bit encoding). An unknown or unreachable pull returns 404. A 404 never distinguishes a missing pull from one your installation cannot reach.

Cost: 1 point against the principal budget (ordinary read).

Path parameters
