# Get Datasets Graph Summary

> Get node/edge counts per dataset, cached per cognify run.

Counts are computed once per dataset's latest cognify run and cached in
GraphMetrics, keyed by pipeline_run_id — orders of magnitude cheaper on
repeat polls than GET /{dataset_id}/graph, which does a full traversal.

## Query Parameters
- **dataset_ids** (List[UUID], optional): Dataset UUIDs to summarize.
  If omitted, summarizes every dataset the user has read permission on.

## Response
Returns a list of summaries containing:
- **datasetId**: The dataset's UUID
- **pipelineRunId**: The dataset's latest cognify run, or null if it
  has never been cognified
- **numNodes** / **numEdges**: Graph size for that run
- **computedAt**: When the count was cached, or null if the last
  attempt degraded (graph store unavailable) and wasn't cached
