How do I get the PDF of a specific research article?

Use the `get_article_pdf` tool with the CORE Article ID. The agent will return the direct download URL for the open access PDF version of the paper.

Can I search for specific journals or repositories?

Yes! You can use `search_journals` or `search_repositories` for general text queries, or use `get_journal` (with an ISSN) and `get_repository` (with a Repository ID) for direct lookups.

What does the OAI resolution tool do?

The `resolve_oai` tool takes an OAI identifier (like oai:oro.open.ac.uk:75049) and resolves it to the CORE metadata page or the original repository link, helping you find the source of the research.
