This repo is an example that sets up a devbox environment with Python and pip. It uses Fast API to set up API endpoints listed below and calls OpenAI API to allow interactions with ChatGPT.

To setup this repo make sure to have devbox installed and have access to your OpenAI's API key.

1. Clone this repo git clone https://github.com/jetify-examples/openai-fastapi.git.
2. cd openai-fastapi and then run devbox run install
3. Copy your OpenAI's API key in devbox.json's "env" section.
4. run devbox run start

Once the server is setup and running, you can access to static page by visiting localhost:8080

The app also makes an API endpoint available to interact with OpenAI's ChatGPT. The endpoint responds to POST requests to /api/prompt. Below is an example request and response:

Example request:

curl --location 'http://127.0.0.1:8080/api/prompt' \
--header 'Content-Type: application/json' \
--data '{
    "prompt": "What is the circumference of Earth?"
}'

Example response:

{
  "message": {
    "content": "The circumference of Earth is approximately 24,901 miles (40,075 kilometers).",
    "refusal": null,
    "role": "assistant",
    "function_call": null,
    "tool_calls": null
  }
}

To use this project as a skeleton and develop on it, you can utilize the references for Fast API docs, more specifically, routes and handlers. As well as OpenAI's Python SDK.
