A Digital Object Identifier (DOI) is a unique alphanumeric string that identifies a digital document, providing a permanent link to scholarly articles, datasets, and reports.

DOICitation fetches metadata from Crossref and OpenAlex APIs using the DOI, then formats it into APA, MLA, Chicago, Harvard, IEEE, BibTeX, or RIS format.
