# Get Edge

GET https://api.getzep.com/api/v2/graph/edge/{uuid}

Returns a specific edge by its UUID.

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

## Request

### Path parameters

- `uuid` (string, required) — Edge UUID

## Response

### 200

Edge

- `created_at` (string, required) — Creation time of the edge
- `fact` (string, required) — Fact representing the edge and nodes that it connects
- `name` (string, required) — Name of the edge, relation name
- `source_node_uuid` (string, required) — UUID of the source node
- `target_node_uuid` (string, required) — UUID of the target node
- `uuid` (string, required) — UUID of the edge
- `attributes` (map from string to any, optional) — Additional attributes of the edge. Dependent on edge types
- `episodes` (list of string, optional) — List of episode ids that reference these entity edges
- `expired_at` (string, optional) — Datetime of when the node was invalidated
- `hyperedge_uuid` (string, optional) — HyperedgeUUID groups the pairwise edges projected from the same atomic multi-entity fact. Omitted when the edge is not part of a hyperedge.
- `invalid_at` (string, optional) — Datetime of when the fact stopped being true
- `relevance` (double, optional) — Relevance is an experimental rank-aligned score in [0,1] derived from Score via logit transformation. Only populated when using cross_encoder reranker; omitted for other reranker types (e.g., RRF).
- `scope` (string, optional) — Scope of the edge (e.g. "entity", "maybe_related")
- `score` (double, optional) — Score is the reranker output: sigmoid-distributed logits [0,1] when using cross_encoder reranker, or RRF ordinal rank when using rrf reranker
- `selection_rank` (integer, optional) — SelectionRank is the global cross-scope rank assigned by auto scope selection.
- `source_node_labels` (list of string, optional) — SourceNodeLabels are the labels of the source node at read time. Same read-time-projection semantics as SourceNodeName.
- `source_node_name` (string, optional) — SourceNodeName is the name of the source node at read time. It is a read-time projection of current node state, not a stored edge attribute: a subsequent node rename is reflected on the next read. Omitted (the edge is still returned) if the source node cannot be resolved, for example if it was deleted concurrently.
- `target_node_labels` (list of string, optional) — TargetNodeLabels are the labels of the target node at read time. Same read-time-projection semantics as SourceNodeName.
- `target_node_name` (string, optional) — TargetNodeName is the name of the target node at read time. Same read-time-projection semantics as SourceNodeName.
- `valid_at` (string, optional) — Datetime of when the fact became true
