Synthetic example. Each line is written when the request is served, with the zone requested, the zone served, the site and the model. CSV and JSON export from the dashboard or through the API.
Three zones, one rule.
The zone is set by the key, and each request can narrow it. The server holds to the key's zone. For each request we keep the time, key, zone, country and model; the content serves only to answer you.

First call.
Change the base URL and the key: your OpenAI SDK does the rest.
1. Change the URL
The OpenAI SDK, in Python, Node or any other language, points at Bretelle.
from openai import OpenAI
client = OpenAI(
base_url="https://api.bretelle.eu/v1",
api_key=BRETELLE_KEY,
)
2. Call a model
The model sets the zone. Every response states the zone and country of processing in its headers.
Key issued at once, €2 free. Card needed at the first purchase only. Operated by Mazlo SAS, Bordeaux, France.

List of sub-processors and sites
Exportable crossing log, per request
Data-flow diagram per zone
To open an account
