AI API for roleplay & character chat

Connect any roleplay or character-chat frontend to one API key and pick from a wide range of chat models — including free ones — with pay-as-you-go pricing. The same key works across SillyTavern, Janitor AI, Chub and RisuAI, so you can switch models without juggling separate provider accounts.

Same code as the OpenAI SDK — change the base URL and key, pick a model id:

from openai import OpenAI

client = OpenAI(
    base_url="https://api.airforce/v1",
    api_key="YOUR_KEY",
)

resp = client.chat.completions.create(
    model="llama-4-scout",
    messages=[{"role": "user", "content": "Hello!"}],
)
print(resp.choices[0].message.content)
