LangChain + TokenBaazar — setup in 3 lines
How to point LangChain's ChatOpenAI class at TokenBaazar.
LangChain's ChatOpenAI takes a base_url. That's the whole setup.
python
from langchain_openai import ChatOpenAI
llm = ChatOpenAI(
model="openai/gpt-5.4-mini",
api_key="sk-tb-...",
base_url="https://tokenbaazar.in/api/public/v1",
)All LangChain chains, tools, and agents work unchanged — LangChain doesn't know or care about the endpoint.
