Quickstart

1 Get a key

Sign in with an email code in the console, create an API key, and top up a prepaid balance (from $10). You pay per token — nothing else.

2 Point your client at us

Change base_url and pass your key. Everything else stays the same.

from openai import OpenAI

client = OpenAI(
    base_url="https://api.unboundmodels.com/v1",
    api_key=os.environ["UNBOUND_API_KEY"],
)

3 Call the model

Use the model id from the catalog. Streaming is recommended: if the model is asleep, the stream opens immediately and keeps your client connected while it wakes (~40 s). Warm-up is never billed — the meter starts with the first generated token.

stream = client.chat.completions.create(
    model="unbound/qwen3.8-27b",
    messages=[{"role": "user", "content": "Hello"}],
    stream=True,
)

for chunk in stream:
    ...

Tool calls, reasoning traces, structured output, and stream_options with include_usage all work exactly as in the OpenAI API. Prompts and completions are not stored.
