freebasic and OpenAI API

[ron77]

ok so two versions of a code one for linux the other for win 32 bit

the code is a simple chatbot that uses libcrul (in linux sudo install libcrul-dev (need to look for right name) ) for win 32 need to have libcrul.dll and credentials file... ) to communicate with OPENAI API you need a OPENAI_API_KEY variable to put in a bash or batch file before executing the executables (both in linux and windows)

version 1 - the linux 64 bit version:

dependencies for linux 64 bit:

sudo apt-get install libcurl4-openssl-dev

for linux use bash script for openai variable:

!#/bin/sh
export OPENAI_API_KEY="..."
./linux-executable

for windows 32 bit use bat file to set variable and run executable

@echo off
