  title: CORE API
  version: 1.0.0
  description: >
    CORE is a memory sharing platform for LLMs with graph-based storage,
    temporal facts, and comprehensive search capabilities.


    ## Authentication


    CORE supports multiple authentication methods:

    - **Bearer Token**: Personal API tokens or OAuth2 access tokens

    - **OAuth2**: Full OAuth2 authorization code flow with PKCE support

    - **Session Cookies**: For web interface access


    Most API endpoints support Bearer token authentication via the Authorization
    header:

    ```

    Authorization: Bearer YOUR_TOKEN_HERE

    ```


    ## Features


    - **Temporal Knowledge Graph**: Store and query facts with temporal validity

    - **Labels**: Organize knowledge with workspace-scoped tags

    - **Search**: Advanced semantic search with graph traversal

    - **Ingestion**: Process and extract facts from various data sources  

    - **Integrations**: Connect with external platforms via OAuth2

    - **MCP Support**: Model Context Protocol for AI assistant integration

    - **Webhooks**: Real-time notifications for data changes
