paper_search([
    {"searcher": "arxiv", "query": "machine learning", "max_results": 5}
])

# Search PubMed Central for biomedical papers
paper_search([
    {"searcher": "pmc", "query": "cancer treatment", "max_results": 5}
])

# Search CORE for open access papers
paper_search([
    {"searcher": "core", "query": "climate change", "max_results": 5}
])

Multi-Platform Search:

# Search multiple platforms simultaneously
paper_search([
    {"searcher": "arxiv", "query": "deep learning", "max_results": 5},
    {"searcher": "pubmed", "query": "cancer immunotherapy", "max_results": 3},
    {"searcher": "pmc", "query": "diabetes treatment", "max_results": 3},
    {"searcher": "semantic", "query": "climate change", "max_results": 4, "year": "2020-2023"}
])

Premium Sources (require API keys):

2. Download Papers (paper_download)

Download paper PDFs using their identifiers:

# Download from free sources
paper_download([
    {"searcher": "arxiv", "paper_id": "2106.12345"},
    {"searcher": "pubmed", "paper_id": "32790614"},
    {"searcher": "pmc", "paper_id": "PMC7419405"},
    {"searcher": "biorxiv", "paper_id": "10.1101/2020.01.01.123456"},
    {"searcher": "semantic", "paper_id": "DOI:10.18653/v1/N18-3011"}
])

# Download from CORE (open access)
paper_download([
    {"searcher": "core", "paper_id": "123456789"}
])

Note: Premium sources (IEEE, Springer, Science Direct, Scopus) require institutional access or subscriptions for PDF downloads.

3. Read Papers (paper_read)

Extract and read text content from papers:

# Read papers from free sources
paper_read(searcher="arxiv", paper_id="2106.12345")
