Tools 3 found in our last check
format_citationFormat one source (a DOI, ISBN, PubMed ID, web address or pasted reference) in a citation style. The answer says whether a published record confirmed it.
check_referencesCheck up to 15 references against Crossref, PubMed, DataCite, DBLP, and OpenAlex. The answer labels each reference verified, not found, mismatch, or unparseable. It lists what differs from the matched record and marks a retracted work.
find_doiFind the registered DOI of one pasted reference. The answer gives a DOI only when its record is the pasted work.
