A user sends a message in the **n8n Chat** UI (public chat trigger).\n2. The **AI Agent** interprets the request.\n3. The agent calls **CoinGecko Free MCP** to fetch market data (prices, coins, trending, etc.).\n4. The model responds through **C1 by Thesys** with a **streaming, UI** answer.\n\n### Example prompts you can try right away\nCopy/paste any of these into the chat:\n\n- \u201cWhat are the products in the catalog?\u201d\n- \"Purchase white shirt\"\n- \"Checkout my cart\"\n\n### How it works\n\n1. User sends a prompt\n2. C1 model based on prompt will use Shopify MCP to fetch live catalog\n3. C1 Model generates a UI Schema Response\n4. Schema is rendered as UI using Thesys GenUI SDK on the frontend\n\n\n### Setup \n\nMake sure you have the following:\n\n#### 1. Thesys API Key\nYou\u2019ll need an API key to authenticate and use Thesys services.\n\nGet your key [here](https://console.thesys.dev/keys) \n\n#### 2. Shopify MCP URL\nYou\u2019ll need the URL of your Shopify Storefront MCP to access the catalog.\n\nFor more information, please refer to the [Shopify MCP Docs](https://shopify.dev/docs/apps/build/storefront-mcp/servers/storefront).\n\n\n### What is C1 by Thesys?\nC1 by [Thesys](https://www.thesys.dev/) is an API middleware that augments LLMs to respond with **interactive UI (charts, buttons, forms)** in real time instead of text.\n\n### Video Tutorial\n\n@[youtube](0rtdVfjKJ-M)\n\n### Facing setup issues?\n#### If you get stuck or have questions:\n\n- #### \ud83d\udcac Join the [Thesys Community](https://discord.com/invite/Pbv5PsqUSv) \n- #### \ud83d\udce7 Email support: support@thesys.dev\n"
