Pyzotero

Pyzotero is a Python wrapper for the Zotero API v3. Use it to programmatically manage Zotero libraries: read items and collections, create and update references, upload attachments, manage tags, and export citations.

Current upstream: pyzotero 1.13.0 (PyPI, May 2026). Docs: pyzotero.readthedocs.io.

Authentication Setup

Required credentials — get from https://www.zotero.org/settings/keys:

• User ID: shown as "Your userID for use in API calls"
• API Key: create at https://www.zotero.org/settings/keys/new
• Library ID: for group libraries, the integer after /groups/ in the group URL

Store credentials in environment variables or a .env file:

ZOTERO_LIBRARY_ID=your_user_id
ZOTERO_API_KEY=your_api_key
ZOTERO_LIBRARY_TYPE=user  # or "group"

See references/authentication.md for full setup details.

Installation

uv add pyzotero              # Web API client
uv add "pyzotero[cli]"       # + local CLI (Zotero 7)
uv add "pyzotero[mcp]"       # + MCP server for LLM clients (Zotero 7)

Quick Start

import os
from pyzotero import Zotero

zot = Zotero(
    library_id=os.environ['ZOTERO_LIBRARY_ID'],
    library_type=os.environ.get('ZOTERO_LIBRARY_TYPE', 'user'),
    api_key=os.environ['ZOTERO_API_KEY'],
)

# Retrieve top-level items (returns 100 by default)
items = zot.top(limit=10)
for item in items:
    print(item['data'][], item[][])


results = zot.items(q=, limit=)


all_items = zot.everything(zot.items())
