inspirehep.net vs isEven (humor)
inspirehep.net
INSPIRE-HEP is the high-energy physics community's literature database, covering papers, authors, institutions, and citation graphs going back decades. Its REST API returns JSON records for literature, author, and conference searches and is fully keyless, with no registration or rate-limit tier to opt into.
isEven (humor)
isEven is a parody of the infamous is-even npm-package controversy, wrapped as a keyless REST endpoint that answers whether a given number is even. The free tier's JSON response bundles in a joke classified ad alongside the boolean result; a paid Premium/Enterprise tier removes the ads.
