description: >
  Cognee is an open-source AI memory and knowledge graph platform that enables developers
  to build persistent, structured memory for AI agents and LLM applications. The platform
  provides a REST API and Python/TypeScript SDKs for ingesting documents and data from
  28+ sources, processing them through a six-stage ECL (Extract, Cognify, Load) pipeline,
  and storing the resulting entities and relationships in a hybrid graph-vector-relational
  store. Developers can query the knowledge graph using 13+ search modes including semantic
  graph completion, RAG completion, and temporal search. Cognee is available as a managed
  cloud service on AWS, GCP, and Azure, or as a self-hosted deployment via Docker, Modal,
  Railway, Fly.io, and Render.

    description: >
      The Cognee REST API provides endpoints for the complete AI memory lifecycle, including
      data ingestion, knowledge graph construction, and semantic retrieval. Core endpoints
      cover adding raw text or documents, triggering the cognify pipeline that extracts
      entities and relationships via LLM, executing multi-mode search queries, managing
      datasets, and creating agent identities. The API uses X-Api-Key header authentication
      for cloud deployments and Bearer token auth for self-hosted instances.
