Platform · API and Gateway

Plug aitnus into your own product.

Keep your OpenAI code. Change the base URL and the key, nothing else. The access and budget rules from chat apply on the API too.

Chat Completions, Responses and Anthropic Messages formats, ready to use. Your team doesn't learn a new SDK.

from openai import OpenAIclient = OpenAI(    base_url="https://your-company.aitnus.com/v1",    api_key="sk_…",)# Same call as before: only the address and the key changed.reply = client.chat.completions.create(    model="gpt-5",    messages=[{"role": "user", "content": "Merhaba"}],)

Keys, rate limits, budget and logs

Every key has its own rate limit, and API spend sits in a budget separate from chat. Traffic logging stays off unless you turn it on.

Questions

Will my existing OpenAI code work?

Yes. Changing the base URL and the key is enough.

Does the API keep chat history?

No. The Gateway is stateless, so your application keeps the conversation history.

Will API costs get out of hand?

No. The API has its own budget and every key its own rate limit. You see spend by model.

Can we use the API without the chat interface?

Yes. In Backend Service Mode the platform runs headless, as an API service only.
