isEven (humor) vs SHARE
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.
SHARE (now internally rebranded "trove", version 26.0.0 as of this check) is the Center for Open Science's free aggregator of metadata about research and scholarly activity, pulling in tens of millions of records from sources like CrossRef and OSF and re-indexing them for keyless search. Its v2 API exposes an Elasticsearch-backed search endpoint plus RSS and Atom feeds, all reachable with no registration.
