This endpoint combines the add and cognify steps. Data is ingested first, then automatically processed into a structured knowledge graph. ## Request Parameters - **data** (List[UploadFile]): Files to upload and process. - **labels** (Optional[str]): JSON array of per-file labels, e.g. ["finance", "people", ""], paired positionally with the uploaded files (one entry per file; an empty entry skips that file). Stored on each file's data record. Normal ingestion only — rejected with session_id or content_type. - **external_metadata** (Optional[str]): JSON array of per-file metadata objects, e.g. [{"source": "crm"}, null], paired positionally with the uploaded files (one entry per file; null or {} skips that file). Merged into each file's stored external_metadata. Normal ingestion only — rejected with session_id or content_type. - **datasetName** (Optional[str]): Name of the target dataset. - **datasetId** (Optional[UUID]): UUID of an existing dataset. - **session_id** (Optional[str]): Session to attribute this memory to. When set, data is stored in the session cache and bridged into the permanent graph in the background; the session is tracked in the sessions dashboard. When omitted, data is ingested directly via add + cognify. - **node_set** (Optional[List[str]]): Node identifiers for graph organisation. - **run_in_background** (Optional[bool]): Run the cognify step asynchronously (default: False). - **custom_prompt** (Optional[str]): Custom prompt for entity extraction. - **chunk_size** (Optional[int]): Maximum tokens per chunk (default: 4096). - **chunks_per_batch** (Optional[int]): Chunks per cognify batch. - **ontology_key** (Optional[List[str]]): Reference to one or more previously uploaded ontology files to use for knowledge graph construction. - **graph_model** (Optional[str]): JSON-serialised graph model schema (same dict format accepted by the cognify endpoint). - **content_type** (Optional[str]): Set to "skills" to ingest SKILL.md files as Skill nodes, or "code" to index whole repositories (see repositories); omit for normal ingestion. - **repositories** (Optional[List[str]]): content_type="code" only — git URLs or server-local repo paths to index as code graphs, one graph per entry. Poll progress via GET /v1/datasets/status?pipeline=code_graph_pipeline. - **index_vectors** (Optional[bool]): content_type="code" only — also embed the extracted code facts for semantic retrievers (default false, no LLM/embedding calls otherwise). Either datasetName or datasetId must be provided. ## Error Codes - **400 Bad Request**: Neither datasetId nor datasetName provided, unsupported content_type, invalid graph_model JSON/schema, or invalid code-ingestion combination (missing repositories, file uploads or session_id with content_type="code", repositories/index_vectors without it, or local repo paths while ACCEPT_LOCAL_FILE_PATH=false) - **409 Conflict**: Error during processing ## OpenAPI ````yaml /cognee_openapi_spec.json post /api/v1/remember openapi: 3.1.0 info: title: Cognee API description: Cognee API with Bearer token and Cookie auth version: 1.0.0 servers: - url: https://api.cognee.ai description: Production server (full functionality) - url: http://localhost:8000 description: Local development server (requires local setup) security: - BearerAuth: [] - ApiKeyAuth: [] tags: - name: activity description: '' - name: add description: Data ingestion endpoints for adding text, files, and structured data. - name: agent connections description: '' - name: agent management description: '' - name: auth description: >- Authentication endpoints for user registration, login, and token management. - name: checks description: '' - name: cognify description: >- Knowledge processing endpoints to transform raw data into knowledge graphs. - name: configuration description: '' - 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: '' - name: health description: '' - name: improve description: '' - name: integrations description: '' - name: llm description: '' - name: memify description: '' - name: ontologies description: '' - name: permissions description: Permission management for multi-user access control. - name: recall description: '' - name: remember description: '' - name: responses description: Response generation endpoints using the knowledge graph. - name: schema description: '' - name: search description: Search endpoints for querying the knowledge graph. - name: sessions description: '' - name: settings description: Configuration endpoints for managing Cognee settings. - name: skills description: '' - name: slack description: '' - name: sync description: '' - name: update description: '' - name: users description: User management endpoints. - name: validate description: '' - name: visualize description: Graph visualization endpoints. paths: /api/v1/remember: post: tags: - remember summary: Remember description: >- Ingest data and build the knowledge graph in a single call.

The comma-separated form "finance,people," is accepted equivalently (it is what Swagger UI sends when you type a JSON array here), so labels cannot contain commas unless the client sends real JSON. Stored on each file's data record and returned when listing dataset data. Only supported for normal ingestion — rejected when combined with session_id or content_type. examples: - '' external_metadata: anyOf: - type: string - type: 'null' title: External Metadata description: >- JSON array of per-file metadata objects, e.g. [{"source": "crm", "ticket": 42}, null]. Paired positionally like labels: the Nth entry applies to the Nth uploaded file (null or {} skips that file), and one entry per file is required when any is given. Merged into the file's stored external_metadata (your keys win over loader-derived ones; 'node_set' is reserved). Only supported for normal ingestion — rejected when combined with session_id or content_type. examples: - '' datasetName: anyOf: - type: string - type: 'null' title: Datasetname description: >- Name of the target dataset (created if it does not exist). Required unless datasetId is provided. examples: - default_dataset datasetId: anyOf: - type: string format: uuid - type: string const: '' - type: 'null' title: Datasetid examples: - '' session_id: anyOf: - type: string - type: 'null' title: Session Id description: >- Session to attribute this memory to (e.g. claude-code-1718000000). When set, the data is stored in the session cache (and bridged into the permanent graph in the background) and the session appears in the sessions dashboard. Leave empty for a direct add+cognify. examples: - '' node_set: anyOf: - items: type: string example: '' type: array - type: 'null' title: Node Set description: >- Tags the ingested data with named node sets (e.g. per-agent or per-project groups). Extracted graph nodes are linked to these sets, and recall/search can later be restricted to them via their node_name parameter. Leave empty to skip tagging. examples: - null run_in_background: anyOf: - type: boolean - type: 'null' title: Run In Background description: >- If true, the request returns immediately (status 'running' with a pipeline_run_id) while ingestion and graph building continue server-side — poll GET /v1/datasets/status to track completion. If false, the request blocks until the knowledge graph is fully built, which can take minutes for large files. default: false custom_prompt: anyOf: - type: string - type: 'null' title: Custom Prompt description: >- Replaces the default entity-extraction prompt used during graph building. Use it to steer which entities and relationships get extracted (e.g. focus on technical concepts, people, or contracts). Leave empty for the default prompt. default: '' chunk_size: anyOf: - type: integer - type: 'null' title: Chunk Size description: >- Maximum tokens per text chunk during ingestion (default: 4096). Each chunk is processed by the LLM separately for entity extraction: larger chunks give more context per extraction but fewer, coarser passes; smaller chunks give finer-grained extraction at higher LLM cost. default: 4096 chunks_per_batch: anyOf: - type: integer - type: 'null' title: Chunks Per Batch description: >- Number of chunks processed per cognify task batch (default: 36). Controls ingestion parallelism/throughput; rarely needs changing. default: 36 ontology_key: anyOf: - items: type: string example: '' type: array - type: 'null' title: Ontology Key description: >- Keys of previously uploaded ontologies (see /v1/ontologies) to ground entity extraction. Leave empty to ingest without an ontology. examples: - [] graph_model: anyOf: - type: string - type: 'null' title: Graph Model description: >- JSON-serialised graph model schema (same format as the cognify endpoint), e.g. {"title": "CompanyGraph", "type": "object", "properties": {...}}. Must include a top-level 'title' key. Leave empty to use the default KnowledgeGraph model — a restrictive schema here can produce an empty graph. Invalid JSON or an unconvertible schema is rejected with 400. examples: - '' content_type: anyOf: - type: string - type: 'null' title: Content Type description: >- Set to 'skills' to ingest SKILL.md files as dataset-scoped Skill nodes, or 'code' to index whole code repositories (pass them via 'repositories') as an architectural code graph through the enola-backed pipeline. Leave empty for normal ingestion. examples: - '' import_mode: anyOf: - type: string - type: 'null' title: Import Mode description: >- COGX archive imports only: 'preserve' (default), 'hybrid', or 're-derive'. examples: - '' skills_text: anyOf: - type: string - type: 'null' title: Skills Text description: >- content_type='skills' only: inline SKILL.md markdown to ingest without a file upload (no-code path). When set and no files are uploaded, it is written to a temporary SKILL.md and ingested via the normal skills pipeline. Pair with skill_name to control the resulting skill name. examples: - '' skill_name: anyOf: - type: string - type: 'null' title: Skill Name description: >- content_type='skills' + skills_text only: name/slug for the inline skill (defaults to 'skill'). examples: - '' repositories: anyOf: - items: type: string example: '' type: array - type: 'null' title: Repositories description: >- content_type='code' only: repository specs to index — remote git URLs (cloned server-side, shallow) or local directory paths on the server's filesystem (requires ACCEPT_LOCAL_FILE_PATH; useful when the server shares the caller's filesystem). One code graph is built per entry. Combine with run_in_background=true for large repositories and poll GET /v1/datasets/status?pipeline=code_graph_pipeline. examples: - null index_vectors: anyOf: - type: boolean - type: 'null' title: Index Vectors description: >- content_type='code' only: also embed the extracted code facts so semantic/completion retrievers can see them (requires an embedding provider). Default false — the code graph pipeline is deterministic and makes no LLM or embedding calls, and SearchType.CODE uses graph indexes only. default: false type: object title: Body_remember_api_v1_remember_post HTTPValidationError: properties: detail: items: $ref: '#/components/schemas/ValidationError' type: array title: Detail type: object title: HTTPValidationError ValidationError: properties: loc: items: anyOf: - type: string - type: integer type: array title: Location msg: type: string title: Message type: type: string title: Error Type input: title: Input ctx: type: object title: Context type: object required: - loc - msg - type title: ValidationError securitySchemes: BearerAuth: type: http scheme: bearer bearerFormat: JWT ApiKeyAuth: type: apiKey in: header name: X-Api-Key ````
