NVIDIA quietly built one of the most impressive AI APIs out there — and most developers don't know it exists.

Setup (60 seconds)

from openai import OpenAI

client = OpenAI ( base_url = " https://integrate.api.nvidia.com/v1 " , api_key = " nvapi-YOUR_KEY_HERE " )

That's it. Get your key at build.nvidia.com . Free tier included.
