Voice and chat booking for any website, addon, agent, or booking stack.

ConSergio is a white-label appointment layer for merchants, agencies, SaaS products, WordPress sites, MCP agents, CLI workflows, custom apps, and existing booking stacks. Customers book by voice or chat; merchants can keep Fresha, Booksy, SevenRooms, OpenTable, Calendly, WordPress booking plugins, Google Calendar, or their current system as the source of truth.

This public tool works without an API key. Owner/private tools use a merchant-scoped key, so a partner can test safely without touching a real client's data.

Public customer tools work without a ConSergio API key. Merchant-owner tools, such as widget snippet generation, require Authorization: Bearer cs_live_....

No calendar required for first launch

If a merchant has not connected Google Calendar yet, ConSergio can still collect service, preferred day/time, customer name, phone, email, and notes, then email the request to the business owner with the customer's address as Reply-To. Calendar sync and Google Meet links can be enabled later.

Trials And Quotas

New merchants can configure and test their real assistant for a limited trial before paying. Public AI sessions, session duration, API usage, and MCP tools are capped by plan. MCP uses deterministic ConSergio API units instead of unpredictable raw LLM token billing.
