OpenAI SDK-Kompatibilität

BazaarLink ist vollständig kompatibel mit den OpenAI Python- und Node.js-SDKs. Nur zwei Änderungen erforderlich:

Vorher (OpenAI direkt)

from openai import OpenAI

client = OpenAI(
    api_key="sk-..."
)

response = client.chat.completions.create(
    model="gpt-4o",
    messages=[...]
)

Nachher (BazaarLink)

from openai import OpenAI

client = OpenAI(
    base_url="https://bazaarlink.ai/api/v1",
    api_key="sk-bl-YOUR_API_KEY"
)

response = client.chat.completions.create(
    model="openai/gpt-4o",  # add provider/
    messages=[...]
)

Das war's!

Alle anderen Funktionen — Streaming, Tool Calling, Structured Output, Async — funktionieren genau gleich. Die einzige Änderung ist base_url, api_key und das Hinzufügen des Anbieter-Präfix zur Modell-ID.

import OpenAI from "openai";

});

async function chat(message: string): Promise<string> {
  const response = await client.chat.completions.create({
    model: "openai/gpt-4o",
    messages: [{ role: "user", content: message }],
  });

}

  process.stdout.write(chunk.choices[0]?.delta?.content ?? "");
}

LangChain

Verwenden Sie BazaarLink mit LangChain, indem Sie die OpenAI-kompatible Base-URL konfigurieren.

from langchain_openai import ChatOpenAI

    api_key="sk-bl-YOUR_API_KEY",
    model="anthropic/claude-sonnet-4.6",
)

response = llm.invoke("Explain BazaarLink in one sentence.")
print(response.content)

LlamaIndex

Verwenden Sie BazaarLink in LlamaIndex-RAG-Pipelines. LlamaIndex unterstützt jeden OpenAI-kompatiblen Endpunkt — ändern Sie einfach zwei Parameter.

    api_base="https://bazaarlink.ai/api/v1",
    api_key="sk-bl-YOUR_API_KEY",
)

# Now use LlamaIndex normally — it calls BazaarLink
from llama_index.core import VectorStoreIndex, SimpleDirectoryReader

documents = SimpleDirectoryReader("./docs").load_data()
index = VectorStoreIndex.from_documents(documents)
query_engine = index.as_query_engine()
response = query_engine.query("What is this documentation about?")
print(response)

Vercel AI SDK

Integrieren Sie das Vercel AI SDK mit BazaarLink in Ihrer Next.js-App. Unterstützt Streaming, Tool Calling und Structured Output.
