zotero-bridge 0.3.0

Python SDK for Zotero debug-bridge

zotero-bridge

Python SDK for the Zotero debug-bridge — programmatically manage your Zotero library via HTTP.

Install

pip install zotero-bridge

Or from source:

git clone https://github.com/Xp-speit2018/zotero-bridge.git
cd zotero-bridge
pip install -e ".[dev]"

Quick start

from zotero_bridge import ZoteroBridge

bridge = ZoteroBridge()

# Lookup existing items
lookup = bridge.lookup("10.1109/DAC63849.2025.11132862", "DOI", include_attachments=True)

# Backward-compatible duplicate check
dup = bridge.check_duplicate("10.1109/DAC63849.2025.11132862", "DOI")

# Add by identifier (magic wand)
item = bridge.add_by_identifier("10.1109/DAC63849.2025.11132862", "DOI")

# Auto-fetch PDF
bridge.find_fulltext(item["itemID"])

# Add note + tag
bridge.add_note(item["itemID"], "Key insight: ...")
bridge.add_tag(item["itemID"], "to-read")

# Download PDF bytes
pdf = bridge.get_pdf_bytes(item["itemID"])

Configuration

Environment variables (optional):

Variable	Default	Description
ZOTERO_BRIDGE_URL	http://localhost:23120	Debug-bridge proxy URL
ZOTERO_BRIDGE_TOKEN	zotero-debug	Bearer token
ZOTERO_LIBRARY_ID	(empty)	Library ID; empty = user library

Or a .env file (requires python-dotenv):

ZOTERO_BRIDGE_URL=http://localhost:23120
ZOTERO_BRIDGE_TOKEN=zotero-debug

CLI lookup

Look up existing Zotero items and print JSON:

zotero-lookup --doi "10.1109/DAC63849.2025.11132862" --attachments --notes
zotero-lookup --title "Attention Is All You Need" --first

CLI ingestion workflow

A ready-made pipeline that checks for duplicates, fetches metadata + PDF, creates DBLP-style venue collections, and aliases items into a project collection:

# Auto-derive venue from metadata
zotero-ingest --doi "10.1109/DAC63849.2025.11132862" --project "MyResearch"

# Or specify venue explicitly (still normalised to DBLP convention)
zotero-ingest --doi "10.1109/DAC63849.2025.11132862" --venue "ASPLOS" --project "MyResearch"

Note that metadata and pdf collection uses the built-in magic wand and Find Full Text functionality, which maybe paywalled or not depending on your network.

API overview

Items

Method	Description
lookup(identifier, id_type, include_notes=False, include_attachments=False, first_only=False)	Look up Zotero items by DOI / ISBN / arXiv / title
check_duplicate(identifier, id_type)	Backward-compatible first-match duplicate check
add_by_identifier(identifier, id_type)	Magic wand ingest
find_fulltext(item_id)	Auto-download PDF
get_item(item_id)	Retrieve metadata
delete_item(item_id)	Trash an item
update_field(item_id, field, value)	Update a single field
add_tag(item_id, tag)	Add a tag
remove_tag(item_id, tag)	Remove a tag

Notes

Method	Description
add_note(item_id, note_text)	Add a child note
get_notes(item_id)	List child notes

Attachments

Method	Description
get_attachments(item_id)	List all attachments with paths
retrieve_pdf(item_id)	Get PDF metadata
get_pdf_bytes(item_id)	Download raw PDF bytes

Collections

Method	Description
create_collection(name, parent_id)	Create a collection
get_collections(parent_id)	List collections
get_or_create_collection(name, parent_id)	Idempotent creation
add_to_collection(item_id, collection_id)	Alias / place item
remove_from_collection(item_id, collection_id)	Remove from collection

Export

Method	Description
export.item(item_id, format, options)	Export a single item
export.items(item_ids, format, options)	Export multiple items
export.collection(collection_id, format, options)	Export a whole collection
export.library(format, options)	Export the entire library
export.list_formats()	List available export formats

Supported formats: better-bibtex, better-biblatex, bibtex, biblatex, ris, csl-json, csv, zotero-rdf, tei, cff.

# Better BibTeX with notes
bib = bridge.export.item(item_id, format="better-bibtex", options={"exportNotes": True})

# Full collection as RIS
ris = bridge.export.collection(collection_id, format="ris")

# Entire library
bib = bridge.export.library(format="better-bibtex")

DBLP venue naming

When the ingestion workflow auto-derives a venue name, it normalises to DBLP convention:

• ISSTA 2023 → issta2023
• ASPLOS 2025, Volume 1 → asplos2025-1
• NeurIPS 2023, Volume 2 → neurips2023-2

A curated mapping of 50+ common venues + DBLP API fallback + local cache handles less common venues automatically.

Requirements

• Python ≥ 3.10
• A running Zotero instance with the debug-bridge extension installed

Acknowledgements

This SDK is built on top of the Zotero debug-bridge extension by Emile Sonneveld / iris-advies.com, originally distributed as part of the zotero-better-bibtex test fixtures. The debug-bridge enables arbitrary JavaScript execution inside a running Zotero instance via an authenticated HTTP endpoint, which is the foundation of everything this SDK does.
