Developer quickstart

Make your first request in minutes. The Upfyn API is OpenAI-compatible, so the SDK you already use works with one base URL and one key.

Get startedCreate API key
from openai import OpenAI
 
client = OpenAI(
    base_url="https://ai.upfyn.com/v1",
    api_key="upfynai-sk-...",          # or os.environ["UPFYN_API_KEY"]
)
 
response = client.chat.completions.create(
    model="upfyn-yuva",
    messages=[
        {"role": "user", "content": "Explain what a gateway does, in two sentences."}
    ],
)
