Hi,

I’m looking for an example to create a FastApi server to serve my graph. One that would work with the Agent Chat UI repo here: langchain-ai/agent-chat-ui: :parrot::speech_balloon: Web app for interacting with any LangGraph agent (PY & TS) via a chat interface.

I know it uses an api based on Langgraph Agent Server.. which is basically what i want to replicate

thanks

Hey, the easiest solution would be to use Agent Server directly. If you really want to reimplement its capabilities, you can find the API documentation here as a starting point: LangGraph Platform API Reference
