Usage Examples

Command Line (Apify)

$apify run

Python Script

from apify import Actor

async with Actor:
    actor_input = {
        "url": "https://arxiv.org/abs/1706.03762",
        "includeAbstract": True
    }
    # ... scraping logic

Test Suite

$python3 test_bibtex.py

Supported Entry Types

• @article - Journal/magazine articles
• @book - Books
• @inproceedings - Conference papers
• @misc - Miscellaneous (fallback)
• @techreport - Technical reports
• @phdthesis - PhD dissertations
• @mastersthesis - Master's theses

Citation Key Generation

Format: firstauthor + year + titleword

Examples:

• vaswani2017attention
• shen2021layoutparser
• smith2023deep

• arXiv ID
• DOI (if published)
• Preprint notation

PubMed Articles

• Title, authors, journal
• Volume, issue, pages
• DOI, PMID
• Publication date

Generic Sites

• JSON-LD structured data
• OpenGraph meta tags
• Twitter Card meta tags
• Dublin Core metadata
• Citation meta tags

Error Handling

• ✅ Missing metadata fields (uses defaults/nulls)
• ✅ Page load failures (returns error object)
• ✅ Timeout scenarios (30s timeout)
• ✅ Special characters (proper escaping)
• ✅ Invalid URLs (validation error)
