Automatically Import Research Papers using DOI URL from Telegram to Zotero

This workflow allows you to automatically import research papers into your Zotero library by simply sending a DOI link through Telegram. It fetches metadata from reliable sources such as Crossref, DataCite, and Unpaywall, enriches the bibliographic details, attaches the best available full-text PDF when possible, and generates a concise summary of the abstract using an LLM before sending it back to Telegram.

✨ Key Features

• Telegram Integration – Send a DOI link via Telegram bot to trigger the workflow.
• DOI Parsing – Automatically detects and extracts DOI or arXiv identifiers from user messages.
• Metadata Fetching – Retrieves bibliographic information from Crossref, DataCite, and Unpaywall.
• Smart PDF Finder – Locates the best available PDF (publisher link, open access, or arXiv).
• Zotero Integration – Creates a Zotero parent item with complete metadata and attaches the PDF link when available.
• Abstract Summarization – Uses a basic LLM chain to generate a short and clear summary of the abstract.
• Telegram Feedback – Sends the title, URL, and abstract summary back to the user in Telegram.

🔑 Required Credentials

• Telegram API – To connect the workflow with your Telegram bot.
• Zotero API Key – To create and update items in your Zotero library.
• OpenRouter API Key – To enable the LLM for generating abstract summaries.
• (Optional) Email for Unpaywall API requests (recommended for stable access).

💡 Benefits

• Save time by automating manual research paper imports.
• Ensure high-quality metadata by combining multiple sources (Crossref, DataCite, Unpaywall).
• Get instant summaries of abstracts directly in Telegram for quick understanding.
• Keep your Zotero library organized with accurate titles, abstracts, authors, and tags.
• Quickly attach available full-text PDFs without manual searching.
• Improve your academic workflow by managing references and summaries directly from Telegram.
