+# Lilo Stitcher API
+
+An ASP.NET Core Web API for stitching, cropping, and scaling tiled images (720×720).
+
+## Prerequisites
+
+* .NET 9.0 SDK
+* `ASSET_PATH_RO` environment variable containing the path to tiles directory (1,705 PNGs named A1.png…AE55.png)
+
+## Build & Run
+
+```bash
+cd lilo-stitcher
+dotnet clean
+dotnet run
+```
+
+By default, the API listens on `http://localhost:5243` and `https://localhost:7121` (see [`launchSettings.json`](https://null.formulatrix.dev/fikribahru/lilo-stitcher/src/branch/main/Properties/launchSettings.json)).
+
+## Usage
+
+**Endpoint:** `POST /api/image/generate`
+
+**Request Body (JSON):**
+
+```json
+{
+  "canvas_rect": "A1:H12",
+  "crop_offset": [0.25, 0.25],
+  "crop_size":   [0.5,  0.5],
+  "output_scale": 1.0
+}
+```
+
+**Example (using `curl`):**
+
+```bash
+curl -X POST http://localhost:5243/api/image/generate \
+     -H "Content-Type: application/json" \
+     -o output.png \
+     -d '{"canvas_rect":"A1:H12","crop_offset":[0.25,0.25],"crop_size":[0.5,0.5],"output_scale":1.0}'
+```
+
+The API will return a `image/png` containing the stitched, cropped, and scaled result.
