Detects orphaned edges (referencing deleted nodes), nodes whose id no longer matches cognee's own dedup contract, and nodes present in the graph but missing from the vector index (unreachable by semantic search). Read-only — never modifies any store. ## Query Parameters - **dataset** (List[str]): Dataset name(s) to validate. Omit to validate the default dataset. ## OpenAPI ````yaml /cognee_openapi_spec.json get /api/v1/validate 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/validate: get: tags: - validate summary: Run Validate description: >- Cross-check the graph and vector stores of a dataset for consistency.
