+# 🗺️ Generate Map Image 
+A Python Cloud Function that generate static map image from longitude and latitude.
+_Example input:_
+```json
+{
+ "lng": 12.561767,
+ "lat": 41.857177
+}
+```
+_Example output:_
+
+```json
+{
+ "success":true,
+ "image":"iVBORw0KGgoAAAANSUhEUgAAAaQAAALiCAY...QoH9hbkTPQAAAABJRU5ErkJggg=="
+}
+```
+## 📝 Environment Variables
+
+List of environment variables used by this cloud function:
+
+**MAPBOX_ACCESS_TOKEN** - Your Mapbox API key.
+
+## 🚀 Deployment
+
+1. Clone this repository, and enter this function folder:
+```
+$ git clone https://github.com/open-runtimes/examples.git && cd examples
+$ cd python/generate-map
+```
+
+2. Enter this function folder and build the code:
+```
+docker run --rm --interactive --tty --volume $PWD:/usr/code openruntimes/python:v2-3.10 sh /usr/local/src/build.sh
+```
+As a result, a `code.tar.gz` file will be generated.
+
+3. Start the Open Runtime:
+```
+docker run -p 3000:3000 -e INTERNAL_RUNTIME_KEY=secret-key -e INTERNAL_RUNTIME_ENTRYPOINT=main.py --rm --interactive --tty --volume $PWD/code.tar.gz:/tmp/code.tar.gz:ro openruntimes/python:v2-3.10 sh /usr/local/src/start.sh
+```
+
+Your function is now listening on port `3000`, and you can execute it by sending `POST` request with appropriate authorization headers. To learn more about runtime, you can visit Python runtime [README](https://github.com/open-runtimes/open-runtimes/tree/main/runtimes/python-3.10).
+
+4. Execute function:
+
+```
+curl http:https://localhost:3000/ -d '{"variables":{"MAPBOX_ACCESS_TOKEN":"YOUR_API_KEY"},"payload": "{\"lng\":50,\"lat\":60}"}' -H "X-Internal-Challenge: secret-key" -H "Content-Type: application/json"
+
+```
+
+## 📝 Notes
+ - This function is designed for use with Appwrite Cloud Functions. You can learn more about it in [Appwrite docs](https://appwrite.io/docs/functions).
+ - This example is compatible with Python 3.10. Other versions may work but are not guaranteed to work as they haven't been tested.
