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 when it wasn't — either the last attempt degraded (graph store unavailable, counts are 0 and retried on the next poll) or a concurrent caller cached the same run first (counts are exact) ## Error Codes - **409 Conflict**: The summary could not be built (generic message; the detail is server-logged rather than returned). A single unreadable graph store does not cause this — that dataset comes back with zero counts — so this means the relational read itself failed. ## OpenAPI ````yaml /cognee_openapi_spec.json get /api/v1/datasets/graph-summary openapi: 3.1.0 info: title: Cognee API description: Cognee API with Bearer token and Cookie auth version: 1.0.0 servers: - url: https://{tenant}.aws.cognee.ai description: 'Cognee Cloud: your tenant pod, named in the platform.cognee.ai dashboard' variables: tenant: default: your-tenant description: Your tenant name, shown in the Cognee Cloud dashboard - url: http://localhost:8000 description: 'Self-hosted: a locally running cognee server' security: - BearerAuth: [] - ApiKeyAuth: [] tags: - name: activity description: >- Activity endpoints for inspecting pipeline runs, traced spans, tenant users, agents, and dataset exports. - name: add description: Data ingestion endpoints for adding text, files, and structured data. - name: agent connections description: >- Endpoints for registering, unregistering, and inspecting agent connections to the instance. - name: agent management description: Endpoints for creating, listing, retrieving, and deleting agents. - name: auth description: >- Authentication endpoints for user registration, login, and token management. - name: checks description: >- Diagnostic endpoint for validating a Cognee Cloud API key supplied in the X-Api-Key header. - name: cognify description: >- Knowledge processing endpoints to transform raw data into knowledge graphs. - name: configuration description: >- Endpoints for storing, retrieving, and listing a user's saved configurations. - name: datasets description: Dataset management endpoints for listing, creating, and deleting datasets. - name: delete description: Data deletion endpoints (deprecated — use datasets endpoints instead). - name: forget description: Endpoint for removing data from the knowledge graph. - name: health description: Liveness, readiness, and component health checks. - name: improve description: Endpoint for enriching and improving an existing knowledge graph. - name: integrations description: >- Endpoints for connecting, provisioning, and disconnecting OAuth providers and plugins. - name: llm description: >- LLM-backed endpoints for inferring graph schemas and generating custom extraction prompts. - name: memify description: >- Endpoint for running enrichment pipelines over existing graphs or supplied data. - name: ontologies description: >- Endpoints for uploading, listing, and deleting ontology files used during cognify. - name: permissions description: Permission management for multi-user access control. - name: recall description: >- Endpoints for querying the knowledge graph and reviewing past recall history. - name: remember description: >- Endpoints for ingesting data into the knowledge graph and storing session memory entries. - name: responses description: Response generation endpoints using the knowledge graph. - name: schema description: >- Schema inspection endpoints for a dataset's derived schema inventory and the caller-wide memory provenance graph. - name: search description: Search endpoints for querying the knowledge graph. - name: sessions description: >- Endpoints for listing sessions and reporting usage, cost, and token statistics. - name: settings description: Configuration endpoints for managing Cognee settings. - name: skills description: >- Skill management endpoints for ingesting, listing, retrieving, and deleting dataset skills, plus read-only retrieval of improvement proposals. - name: slack description: >- Endpoints for listing workspace channels, setting channel allowlists, and linking Slack accounts. - name: sync description: Endpoints for syncing local data to Cognee Cloud and checking sync status. - name: update description: Endpoint for updating existing data in a dataset. - name: users description: User management endpoints. - name: validate description: >- Diagnostic endpoint for checking consistency between a dataset's graph and vector stores. - name: visualize description: Graph visualization endpoints. paths: /api/v1/datasets/graph-summary: get: tags: - datasets summary: Get Datasets Graph Summary description: >- Get node/edge counts per dataset, cached per cognify run.
