LangGraph SDK

Prerequisites

The LangGraph Platform provides both a Python and JS SDK for interacting with the LangGraph Server API.

Installation

You can install the packages using the appropriate package manager for your language.

pip install langgraph-sdk

yarn add @langchain/langgraph-sdk

API Reference

You can find the API reference for the SDKs here:

Python Sync vs. Async

The Python SDK provides both synchronous (get_sync_client) and asynchronous (get_client) clients for interacting with the LangGraph Server API.

from langgraph_sdk import get_client

client = get_client(url=..., api_key=...)
await client.assistants.search()

from langgraph_sdk import get_sync_client

client = get_sync_client(url=..., api_key=...)
client.assistants.search()
