Using GPT to chat with HERE's discover endpoint

Prerequisites

OPENAI_API_KEY and HERE_API_KEY need to be set in environment variables.

What does the script do?

For a user question like

"In which districts in Berlin are streets named Kastanienallee?"

the script uses GPT to create an API call like

https://discover.search.hereapi.com/v1/discover?at=52.5200,13.4050&q=Kastanienallee%20Berlin

Based on the API response, GPT is then used to create a response like the following:

"Streets named Kastanienallee can be found in the following districts in Berlin: Prenzlauer Berg, Rosenthal, Hellersdorf, Westend, and Blankenburg."
