Travel Chatbot Using API

A multi-turn travel chatbot powered by the OpenAI Chat Completions API. Acts as a virtual Parisian expert for Peterman Reality Tours, answering a series of travel questions while maintaining full conversation history across turns.

What it demonstrates

• System prompts — defining an assistant persona
• Multi-turn memory — appending each question and answer to messages so the model has full context on every call
• Chat Completions API — structured messages list with user / assistant / system roles

Sample output

User:  How far away is the Louvre from the Eiffel Tower (in miles) if you are driving?
System:  Ah, what a wonderful question! The Louvre Museum and the Eiffel Tower are both iconic
landmarks in the heart of Paris...

User:  Where is the Arc de Triomphe?
System:  The Arc de Triomphe stands majestically at the western end of the Champs-Élysées...
