Python · OpenAI SDK

from openai import OpenAI

client = OpenAI(base_url="https://api.tokenspend.dev/v1", api_key=os.environ["TOKENSPEND_RAIL_KEY"])
resp = client.chat.completions.create(
    model="openai/gpt-5.6-sol",
    messages=[{"role": "user", "content": "hello"}],
)

Both dialects reach every model: send Anthropic-shaped requests or OpenAI-shaped requests and the rail translates. Prompts and responses are never stored.
