  title: Agno AgentOS Agents Sessions API
  description: 'AgentOS is Agno''s self-hostable runtime and API server. It turns agents, teams, and workflows defined with the open-source Agno Python framework into a RESTful API exposing runs, sessions, memory, knowledge, and evals. There is no single Agno-operated multi-tenant base URL - every AgentOS instance runs on infrastructure you control, defaulting to http://localhost:7777 in local development. When a Security Key (OS_SECURITY_KEY) is configured, all routes require an "Authorization: Bearer <token>" header; otherwise authentication is disabled. This document models the endpoints described in Agno''s public API reference (docs.agno.com/reference-api) plus the sibling endpoints named in Agno''s own documentation index (docs.agno.com/llms.txt). Some request/response field names are reconstructed from that reference content rather than a downloaded machine-readable OpenAPI file, so treat schemas as representative rather than byte-exact.'
