### get_article

Fetch metadata for a single ScienceDirect article by its PII (Publisher Item Identifier), DOI, or ScienceDirect URL. Returns the article title, authors, publisher, journal name, DOI, abstract text, PDF download URL, volume, pages, year, ISSN, and article URL. One upstream request per call when using PII or URL; two requests when resolving a DOI. Cloudflare protection is solved automatically. At least one of pii, doi, or url must be provided.

**Estimated cost:** Metered
