Get an Origin Pull Request Comment via the API

Fetch one comment by stable id with GET https://api.cursor.com/v1/origin/repos/{ownerSlug}/{repoName}/pulls/comments/{commentId}. Official reference: Origin API → Get Pull Request Comment (OpenAPI OriginService_GetPullRequestComment). Changelog notes: August 29, 2026 (full thread object on each comment), September 16, 2026 (OpenAPI schema renamed Thread → CommentThread; wire JSON unchanged).

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

The path addresses the comment by commentId under the repository — there is no pullNumber in this path. A comment outside the authorized repository, or a pending-review comment not visible to the caller, returns 404. A 404 never distinguishes a missing comment from one your installation cannot reach.

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

Path parameters

Param	Required	Meaning
ownerSlug	yes	Owning entity's unique slug
repoName	yes	Repo name, unique to the owner
commentId	yes	Stable Origin comment id (e.g. cmt_…)
