SHARE vs World Bank

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.

The World Bank's Indicators API gives free, keyless REST access to the World Development Indicators dataset — thousands of economic, social, and environmental indicators across nearly 300 countries and regions, spanning six decades. Responses are paginated JSON or XML, covering countries, regions, income levels, lending types, topics, sources, and the indicator series themselves.
