Agno AgentOS Workflows API

  title: Agno AgentOS 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.
