Why It Matters for AI Agents

AI platforms like ChatGPT Actions, Gemini Extensions, and Copilot can consume OpenAPI specs to automatically discover and use APIs. This means any AI assistant can find FlowCaptain's tools — check availability, book, cancel, reschedule — without manual configuration.

Combined with MCP support, FlowCaptain is now discoverable through two industry standards:

  • MCP — for voice bot platforms (Retell, VAPI, Fonio)
  • OpenAPI — for AI assistants and developer integrations

What's Documented

All public endpoints for availability checks, bookings, cancellations, reschedules, service listings, appointment lookups, and calendar status — plus a separate admin section for business management.
