Connor BraaandGitHub 60e305596d feat(sdk-py): add return_minimal to threads update (#7704)
Adds a first-class `return_minimal` option to the Python
`threads.update` clients. When enabled, the SDK sends `Prefer:
return=minimal` and returns `None` for the 204 response. Covers both
async and sync clients with focused tests.

LangGraph Python SDK

This repository contains the Python SDK for interacting with the LangSmith Deployment 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)
