Do I need an API key or any registration to use PubMed?

No. PubMed E-utilities are freely accessible to everyone without registration. An optional API key (available at ncbi.nlm.nih.gov) increases your rate limit from 3 to 10 requests per second, but is not required for standard usage.

What types of searches are supported and how can I refine my results?

You can search by keyword, disease name, gene symbol, drug name, author surname, or journal title. Boolean operators (AND, OR, NOT) and field tags like [Title], [Author], and [MeSH Terms] work natively. Example: 'CRISPR AND cancer NOT review' targets original research on CRISPR in oncology.

Can I access full-text articles through this server?

This server returns complete abstracts and metadata for all indexed articles. Full-text access depends on publisher open access policies — articles from PubMed Central (PMC) are freely available. The DOI link provided with each result allows direct navigation to the publisher's page.
