description: Chatsimple (now operating as Expertise AI, expertise.ai) is an AI agent platform for revenue and go-to-market
  teams. It builds no-code conversational AI sales agents and chatbots that engage website visitors, qualify and capture leads,
  book meetings, and answer questions from a trained knowledge base, plus a Voice AI assistant and an "Expertise Assistant"
  library of 100+ pre-built GTM plays that automate prospecting, pipeline management, and outreach. The platform embeds on
  any website, integrates with CRM and communication tools such as HubSpot, Salesforce, Slack, Zapier, Marketo, and LeanData,
  and offers API access on its Enterprise tier. It is SOC 2 Type II, SOC 3, GDPR, and CCPA aligned with a public trust center.
  Originally launched as chatsimple.ai, the company rebranded to Expertise AI; chatsimple.ai now redirects to expertise.ai.

  name: Expertise AI Zapier / Leads API
  description: 'The only publicly documented HTTP endpoints Chatsimple (now Expertise AI) publishes. Documented on the Zapier
    integration page of docs.expertise.ai as four operations under the base URL https://api.expertise.ai/v0/users: a connect/authorize
    call (GET /zapier), webhook registration (POST /zapier/subscribe with the callback in X-HOOKURL), webhook removal (DELETE
    /zapier/unsubscribe), and retrieval of the most recent captured lead (GET /zapier/get_leads). Every call carries an X-API-KEY
    header plus X-USER-ID and X-CHATBOT-ID to scope it to one account and one agent. Lead payloads carry created_on, name,
    email, phone_number and questions. No OpenAPI is published for it, and on 2026-08-13 every documented path returned HTTP
    404 to an anonymous request while the host itself was healthy — recorded as published but unverified.'

  name: Expertise AI MCP Server
  description: A remote Model Context Protocol server at https://api.expertise.ai/mcp, found by direct probe of the API host
    root and documented nowhere on the provider's site. It implements the MCP Streamable HTTP transport — a GET returns HTTP
    405 with {"error":"SSE stream not supported"} and a POST returns well-formed JSON-RPC 2.0 — but every anonymous call,
    including tools/list, returns HTTP 401 with JSON-RPC error -32001 Unauthorized, so the live tool manifest and its input
    schemas are not publicly readable. The server implements the RFC 8414 and RFC 9728 discovery routes and answers both with
    {"error":"oauth_not_supported"}, so authentication is an API key rather than OAuth. No tool list has been derived or invented.

  note: Round 2. Contract discovery on the API host root found a real remote MCP server (auth-gated) and a real four-endpoint
    REST reference on the Zapier docs page; no OpenAPI, no AsyncAPI, no agent card, no security.txt.
