  title: Cognee REST agents data API
  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.
