Use the same OpenAI-compatible request shape and choose the model that fits your cost and quality target.
from openai import OpenAI
client = OpenAI(
api_key="$CLAUDEN_API_KEY",
base_url="https://clauden.ai/v1",
)
resp = client.chat.completions.create(
model="gpt-4o-mini",
messages=[{"role": "user", "content": "Summarize this in one paragraph"}],
)
print(resp.choices[0].message.content)
Who it fits / who it does not fit
Good fit
Developers, freelancers and startups that need no-card payments, multi-model access, OpenAI-compatible routing and prepaid USDT/PayPal balance.
Not a fit
If you must use only direct official provider accounts, enterprise private contracts or zero third-party gateway, work directly with model providers.
