# Get hyperedge

GET https://api.getzep.com/api/v4/graphs/{graph_uuid}/hyperedges/{hyperedge_uuid}

Returns one hyperedge assembled from its member edges. The fact and the
validity timestamps are shared by every member and are reported on the
hyperedge; each member reports only its own name and endpoints.

Reference: https://docs-beta.getzep.com/sdk-reference/graph/hyperedge/get

## Authentication

- `Authorization` header (required) (prefixed with ` Api-Key  `) — Type "Api-Key" followed by a space and the project API key.

## Request

### Path parameters

- `graph_uuid` (string, required) — Graph UUID
- `hyperedge_uuid` (string, required) — Hyperedge UUID

## Response

### 200

OK

- `created_at` (string, optional) — The time the hyperedge was created. Every member edge shares this value.
- `edges` (list of v4.HyperedgeEdge, optional) — The member edges, ordered by uuid. Each carries only its own identity and endpoints; the shared fact and timestamps are on the hyperedge.
- `expired_at` (string, optional) — The time the fact was superseded or removed.
- `fact` (string, optional) — The natural-language fact this hyperedge represents. Every member edge carries the same fact.
- `graph_uuid` (string, optional) — The unique identifier of the graph this hyperedge belongs to.
- `invalid_at` (string, optional) — The time at which the fact stopped being true.
- `uuid` (string, optional) — The unique identifier of the hyperedge.
- `valid_at` (string, optional) — The time from which the fact is considered true.
