+## ⚡ Quick Requests with `yapi send`
+
+Don't want to create a file? Use `yapi send` for one-off requests directly from the command line.
+
+```bash
+# Simple GET
+yapi send https://jsonplaceholder.typicode.com/posts/1
+
+# POST with JSON body (method auto-detected when body is provided)
+yapi send https://httpbin.org/post '{"title":"Hello from yapi"}'
+
+# Explicit method, custom headers
+yapi send -X PUT https://httpbin.org/put '{"updated":true}' \
+  -H 'Authorization: Bearer my-token'
+
+# Filter response with jq
+yapi send https://jsonplaceholder.typicode.com/posts/1 --jq '.title'
+
+# TCP request
+yapi send 'tcp://tcpbin.com:4242' 'Hello from yapi!'
+```
+
+**Flags:**
+- `-X, --method` - HTTP method (default: GET, or POST if body is provided)
+- `-H, --header` - Custom headers (repeatable, e.g. `-H 'Key: Value'`)
+- `-v, --verbose` - Show request details, timing, and response headers
+- `--json` - Output full result as JSON with metadata
+- `--jq` - Apply a JQ filter to the response
+
+Transport is auto-detected from the URL scheme: `tcp://` for TCP, `grpc://` for gRPC, and HTTP by default.
