# Ask the other institution to review a match

POST https://api.withverifa.com/api/v1/consortiums/{consortium_id}/matches/{match_id}/peer-review-request

Asks the other organization involved in this match to review its own
side and record a determination.

Face images are never shared between consortium members, so when a
human needs a second opinion on a borderline match (a near-threshold
similarity, a suspected sibling or twin) this moves the *question*
rather than the applicant's photo: the peer looks at the record it
already holds, and only their investigation status crosses the
organization boundary.

Idempotent for 24 hours — re-requesting while a request is still
outstanding returns `already_pending` and does not re-notify the peer.
The pending state is visible on the match as
`peer_investigation.review_requested_at`.
