Community SDK Installation

Zep provides SDKs for Python, TypeScript, and Go.

Python

This is the guide for installing sdks for Zep Community Edition (>=v1.0.0).

If you are using Zep Cloud, please refer to the Zep Cloud SDK Installation guide.

If you are using an older version of Zep Open Source, please refer to Legacy SDK Installation guide and consider upgrading to the latest version.

pip

poetry

1 pip install zep-python

TypeScript

npm

yarn

pnpm

1 npm install @getzep/zep-js

Initialize Client

The default base URL for the Zep client is http://localhost:8000.

Python

TypeScript

Go

Zep also offers an async client for Python. To use the async client, import AsyncZep instead of Zep.

1 import os
2 from zep_python.client import Zep
3 
4 API_KEY = os.environ.get('ZEP_API_KEY')
5 BASE_URL = os.environ.get('ZEP_BASE_URL')
6 
7 client = Zep(
8     api_key=API_KEY,
9     base_url=BASE_URL
10 )

The Python SDK Supports Async Use

In order to use async client, you will need to import AsyncZep instead of Zep.

1 from zep_python.client import AsyncZep

Usage Example

Python

TypeScript

1 import uuid
2 from zep_python.client import AsyncZep
3 from zep_python.types import Message
4 
5 client = AsyncZep(
6     api_key=API_KEY,
7     base_url=BASE_URL,
8 )
9 
10 user_id = uuid.uuid4().hex # A new user identifier
11 new_user = await client.user.add(
12     user_id=user_id,
13     email="[email protected]",
14     first_name="Jane",
15     last_name="Smith",
16     metadata={"foo": "bar"},
17 )
18 
19 # create a chat session
20 session_id = uuid.uuid4().hex # A new session identifier
21 session = await client.memory.add_session(
22     session_id=session_id,
23     user_id=user_id,
24     metadata={"foo" : "bar"}

43

45 search_response = await client.memory.search_sessions(
46     user_id=user_id,
47     search_scope="facts",
48     text="What science fiction books did I recently read?",
49 )
