How it works:
1. You ask an agent a question in this widget
2. Relevant knowledge chunks are retrieved client-side (keyword + category matching)
3. Question + retrieved chunks sent to your Cloudflare Worker at mortgageiq-proxy.sma-0a3.workers.dev
4. Worker adds your encrypted API key and forwards to Anthropic
5. Claude answers with full document detail — sources shown below each response
Security: Your API key never touches the browser. It lives encrypted inside Cloudflare. Cost: Cloudflare Workers free tier = 100,000 requests/day. Scaling: As Zoho KB is indexed and vector count grows, the Worker will be upgraded to query Pinecone for semantic search instead of client-side keyword matching.
