+### ⚡ Cloudflare Worker (Streaming Works!)
+
+> **Streaming endpoints work on Workers** — requests to Miruro bypass Cloudflare bot detection because Workers run on Cloudflare's edge network (edge-to-edge traffic is trusted).
+
+```bash
+# Install wrangler CLI
+npm install -g wrangler
+
+# Login to Cloudflare
+wrangler login
+
+# Deploy
+wrangler deploy worker.js --name miruroapi
+```
+
+Your API is live at: `https://miruroapi.YOUR_SUBDOMAIN.workers.dev`

+| Feature | Vercel | Cloudflare Worker |
+|---------|--------|-------------------|

+| Free tier | Unlimited | 100K req/day |
+| npm deps | Yes | No (native fetch) |
+
+> See `worker.js` for the full Worker implementation with 15 endpoints.
