+# vcad Render API
+
+HTTP API that renders [Compact IR](https://campedersen.com/cad0) to PNG images using the vcad kernel.
+
+## Endpoints
+
+### POST /render
+
+Renders Compact IR to a PNG image.
+
+**Request:**
+```json
+{
+  "ir": "C 50 30 10\nY 5 20\nT 1 25 15 0\nD 0 2"
+}
+```
+
+**Response:** PNG image (image/png)
+
+### GET /health
+
+Health check endpoint.
+
+**Response:**
+```json
+{"status": "ok"}
+```
+
+## Compact IR Syntax
+
+- `C w h d` - Box (cuboid)
+- `Y r h` - Cylinder
+- `S r` - Sphere
+- `T idx x y z` - Translate node at index
+- `U a b` - Union of nodes a and b
+- `D a b` - Difference (a minus b)
