3## Overview
4
5This val is a proxy server that interacts with the OpenAI API to generate responses based on prompts in the request body. The function handles incoming HTTP POST requests, processes the prompt, and returns a response generated by the LLM.

7## Prerequisites
14### Endpoint
15
16The primary endpoint for this function is designed to handle HTTP POST requests.

3The `discordBot` function takes in an object where each key is a Discord command and the value is a function to handle the command. If the function returns a `Promise`, it will be handled as a deferred interaction with a [followup message](https://discord.com/developers/docs/interactions/receiving-and-responding#followup-messages).
