How can I find the DOI or PMID for a specific PMCID?

Use the `convert_ids` tool. Simply provide the PMCID (e.g., PMC5334499) and it will return the corresponding PMID, DOI, and other associated identifiers.

Can I get direct download links for research papers?

Yes! The `oa_discover` tool allows you to find downloadable resources like PDFs or XML files for articles in the PMC Open Access Subset using their PMCID.

How do I retrieve the full metadata for a specific article?

Use the `oai_get_record` tool with the article's OAI identifier and a metadata prefix like 'pmc' or 'oai_dc' to fetch the complete record details.
