Where developers can use it

Google lists these official surfaces first. bnrouter is an optional OpenAI-compatible gateway in front of connected upstream accounts.

bnrouter, if the operator has connected an upstream that serves this model. The plaza may still show coming soon — confirm the id in the console or GET /v1/models.

How to call it through bnrouter

bnrouter is an OpenAI-compatible AI API gateway. Create an API key in the console, then send requests to the gateway base URL. Chat completions may not be the right request shape for image or video generation — see the Image & video API docs for the images format this site already documents. This repository does not yet record a gateway model id — copy the id shown in the console (or from GET /v1/models) into the model field. The plaza listing may still show coming soon.

curl

curl https://www.bnrouter.com/v1/chat/completions \
  -H "Authorization: Bearer $YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "YOUR_MODEL_ID",
    "messages": [{"role": "user", "content": "Hello!"}]
  }'

Python (OpenAI SDK)

from openai import OpenAI

client = OpenAI(
    api_key="YOUR_API_KEY",
    base_url="https://www.bnrouter.com/v1",
)

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

Replace YOUR_API_KEY and YOUR_MODEL_ID with values from the console. Do not assume a model id that is not listed there.
