This PR adds an aclose method to the LangGraphClient. When using the client in a FastAPI application, it's common to share a single instance across the application's lifespan. The absence of an aclose method makes it difficult to gracefully close the underlying HTTP session on application shutdown. This change enables proper resource management by allowing the client to be closed cleanly.
LangGraph Python SDK
This repository contains the Python SDK for interacting with the LangGraph Platform REST API.
Quick Start
To get started with the Python SDK, install the package
pip install -U langgraph-sdk
You will need a running LangGraph API server. If you're running a server locally using langgraph-cli, SDK will automatically point at http://localhost:8123, otherwise
you would need to specify the server URL when creating a client.
from langgraph_sdk import get_client
# If you're using a remote server, initialize the client with `get_client(url=REMOTE_URL)`
client = get_client()
# List all assistants
assistants = await client.assistants.search()
# We auto-create an assistant for each graph you register in config.
agent = assistants[0]
# Start a new thread
thread = await client.threads.create()
# Start a streaming run
input = {"messages": [{"role": "human", "content": "what's the weather in la"}]}
async for chunk in client.runs.stream(thread['thread_id'], agent['assistant_id'], input=input):
print(chunk)
