# Get Observation

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

Returns a specific observation node by UUID. Observation nodes are read-only.

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

## Request

### Path parameters

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

## Response

### 200

Observation

- `created_at` (string, required) — Creation time of the node
- `name` (string, required) — Name of the node
- `uuid` (string, required) — UUID of the node
- `attributes` (map from string to any, optional) — Additional attributes of the derived node.
- `end_at` (string, optional) — EndAt is the close timestamp of the evidence window. Set when the underlying pattern is no longer supported (closed observations); nil for active observations.
- `episode_ids` (list of string, optional) — Episode UUIDs that support this observation. Only populated for observation nodes in web API responses.
- `labels` (list of string, optional) — Labels associated with the node
- `latest_evidence_at` (string, optional) — LatestEvidenceAt is the most recent source-episode timestamp from which this observation drew evidence.
- `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).
- `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.
- `start_at` (string, optional) — StartAt is the earliest source-episode timestamp from which this observation was derived. Only populated for observation nodes.
- `summary` (string, optional) — Region summary of member nodes
