# Pyzotero

Pyzotero is a Python wrapper for the [Zotero API v3](https://www.zotero.org/support/dev/web_api/v3/start). Use it to programmatically manage Zotero libraries: read items and collections, create and update references, upload attachments, manage tags, and export citations.

## 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](references/authentication.md) for full setup details.

## Installation

```bash
uv add pyzotero
# or with CLI support:
uv add "pyzotero[cli]"
```

## Quick Start

```python
from pyzotero import Zotero

zot = Zotero(library_id='123456', library_type='user', api_key='ABC1234XYZ')

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

# Search by keyword
results = zot.items(q='machine learning', limit=20)

# Retrieve all items (use everything() for complete results)
all_items = zot.everything(zot.items())
```

## Core Concepts

- A `Zotero` instance is bound to a single library (user or group). All methods operate on that library.
- Item data lives in `item['data']`. Access fields like `item['data']['title']`, `item['data']['creators']`.
- Pyzotero returns 100 items by default (API default is 25). Use `zot.everything(zot.items())` to get all items.
- Write methods return `True` on success or raise a `ZoteroError`.

## Common Patterns

### Fetch and modify an item
```python
item = zot.item('ITEMKEY')
item['data']['title'] = 'New Title'
zot.update_item(item)
```

### Create an item from a template
```python
template = zot.item_template('journalArticle')
template['title'] = 'My Paper'
template['creators'][0] = {'creatorType': 'author', 'firstName': 'Jane', 'lastName': 'Doe'}
zot.create_items([template])
```

### Export as BibTeX
```python
zot.add_parameters(format='bibtex')
bibtex = zot.top(limit=50)
# bibtex is a bibtexparser BibDatabase object
print(bibtex.entries)
```

### Local mode (read-only, no API key needed)
```python
zot = Zotero(library_id='123456', library_type='user', local=True)
items = zot.items()
```
