Evidence-backed facts

  1. The REST base URL https://api.crossref.org/ serves JSON scholarly metadata deposited by members and trusted sources, including funding, licenses, updates, ORCID and ROR identifiers, and abstracts. informative
  2. Crossref states that REST access needs no sign-up. Its quick-start polite-pool example uses the mailto query parameter to identify the caller. informative
  3. The documented /works/{doi} route returns one DOI record; /works/{doi}/agency identifies its registration agency, and /journals/{issn}/works selects a journal's works. The quick start uses rows=10 to request ten items. informative
  4. Crossref warns that some abstracts in the metadata may carry publisher or author copyright; metadata availability alone does not establish permission to reuse those abstracts. informative
