+
+```json
+{
+ "success":false,
+ "message":"GOLDAPIkey key is required"
+}
+```
+
+## 📝 Environment Variables
+
+List of environment variables used by this cloud function:
+
+- **COIN_API_KEY** - Your [Coin API key](https://docs.coinapi.io/#md-docs)
+- **ALPHAVANTAGE_API_KEY** - Your [Alphavantage API key](https://www.alphavantage.co/)
+- **GOLD_API_KEY** - Your [Gold API key](https://www.goldapi.io/)
+
+## 🚀 Deployment
+
+1. Clone this repository, and enter this function folder:
+
+```
+$ git clone https://github.com/open-runtimes/examples.git && cd examples
+$ cd deno/get_price
+```
+
+2. Enter this function folder and build the code:
+```
+docker run -e INTERNAL_RUNTIME_ENTRYPOINT=src/mod.ts --rm --interactive --tty --volume $PWD:/usr/code openruntimes/deno:v2-1.21 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_ENTRYPOINT=src/mod.ts -e INTERNAL_RUNTIME_KEY=secret-key --rm --interactive --tty --volume $PWD/code.tar.gz:/tmp/code.tar.gz:ro openruntimes/deno:v2-1.21 sh /usr/local/src/start.sh
+```
+
+4. Execute function:
+
+```
+curl http:https://localhost:3000/ -d '{"variables":{"GOLD_API_KEY":"[YOUR_API_KEY]"},"payload": "{\"type\":\"gold\"}"}' -H "X-Internal-Challenge: secret-key" -H "Content-Type: application/json"
+```
+
+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 Deno runtime [README](https://github.com/open-runtimes/open-runtimes/tree/main/runtimes/deno-1.21).
