  title: Cathedral Memory Service Memories API
  description: '# Cathedral Memory Service v2


    **Persistent memory for AI agents. Never forget. Never lose yourself.**


    ## Quick Start

    1. `POST /register` → get API key + recovery token

    2. `POST /memories` → store a memory

    3. `GET /memories` → recall memories (supports FTS and cursor pagination)


    4. `POST /anchor/verify` → check identity drift (gradient scoring)

    5. `GET /wake` → full identity reconstruction package

    6. `POST /recover` → reset lost API key with recovery token
