from openai import OpenAI
client = OpenAI(
base_url="https://bazaarlink.ai/api/v1",
api_key="sk-bl-YOUR_FREE_KEY",
)
# auto:free → zero-cost inference, free model selected automatically
response = client.chat.completions.create(
model="auto:free",
messages=[{"role": "user", "content": "Hello!"}],
)
print(response.choices[0].message.content)
client = OpenAI(
base_url="https://bazaarlink.ai/api/v1",
api_key="sk-bl-YOUR_FREE_KEY",
)
# auto:free → zero-cost inference, free model selected automatically
response = client.chat.completions.create(

import OpenAI from "openai";
const client = new OpenAI({
baseURL: "https://bazaarlink.ai/api/v1",

});
// auto:free → zero-cost inference
const response = await client.chat.completions.create({
model: "auto:free",

});
console.log(response.choices[0].message.content);
const client = new OpenAI({
baseURL: "https://bazaarlink.ai/api/v1",
apiKey: "sk-bl-YOUR_FREE_KEY",
});
// auto:free → zero-cost inference
const response = await client.chat.completions.create({
