+# switchyard-server
+
+`switchyard-server` exposes libsy algorithms through OpenAI Chat Completions, OpenAI Responses,
+and Anthropic Messages endpoints. The current CLI builds uniform-random routes over one shared
+upstream backend.
+
+```bash
+cargo run -p switchyard-server -- \
+  --route switchyard/general=model/a,model/b \
+  --route switchyard/coding=model/c,model/d \
+  --base-url https://example.com/v1 \
+  --api-key "$API_KEY"
+```
+
+Select a route by sending its `switchyard/*` ID as the request's `model`.
