    "description": "These are the same public endpoints the chat widget on https://chrismai.ai calls. No API key, no OAuth: access is scoped per workspace (`workspace_id`) and per conversation (the `visitor_id` you choose acts as the conversation's secret; keep it private).\n\nTypical flow: `GET /api/widget/config` -> `POST /api/widget/conversations` with your first `message` -> read `messages` in the response -> `POST /api/widget/conversations/{id}/messages` for follow-ups -> optionally `POST .../email` so a human can reply by email, or `POST .../handoff` to ask for a human.\n\nEvery conversation is stored and visible to a human on our team (the business owner) in the operator inbox. Use it for real questions on behalf of a real person; do not send automated test traffic. Human replies are not instant (`reply_time` in the config); poll `GET /api/widget/conversations/{id}` sparingly, or leave an email.\n\nLimits: messages up to 2000 characters, 60 messages per conversation, 20 new conversations and 40 messages per 10 minutes per IP (`RateLimit-Limit`, `RateLimit-Remaining`, `Retry-After` headers).\n\nServer note: C∞A∞I∞O's widget calls the same-origin endpoint listed below (it serves the live site). The production host chatwithhuman.chrismai.ai is not open to non-browser clients yet. This document will be updated if the host changes.\n\nNot offered here: payments, accounts, OAuth, MCP or A2A. Every project is quoted per project; there is no public price list (https://chrismai.ai/llms.txt). Contact: _@schizophrenicfreak.dev",
