+## Setup
+
+This sample requires an API key to access the OpenAI API. The name of the config value is referenced in the compose.yaml file.
+To provide a value for it, you can use the Defang CLI like this:
+
+```
+
+defang config set --name OPENAI_KEY
+```
+
+and then enter the value when prompted.
+
+## Testing
+
+```
+echo "Hello" | curl -H "Content-Type: text/plain" -d @- https://xxxxxxxx/prompt
+```
+
+or
+
+```
+cat prompt.txt | curl -H "Content-Type: application/text" -d @- https://xxxxxxxx/prompt
+```
+

+
+Title: Node.js & OpenAI
