  title: Persona Ingestion Users API
  version: 1.0.0
  description: 'Persona is an open-source (MIT) user-memory system for AI agents, built by Eder Labs. It ingests raw content (conversations, notes) for a user, extracts a Graph-Vector hybrid memory (Neo4j graph + vector embeddings), and answers natural-language RAG queries or returns structured insights over that memory. This specification is transcribed faithfully from the published FastAPI router source (server/routers/graph_api.py) and the docs/API.md reference of github.com/saxenauts/persona. Persona is self-hosted: the base URL below is the documented local default; deploy behind your own host and auth layer.'
