NewsAPI.ai (Event Registry) vs Mediastack: overview
NewsAPI.ai (Event Registry)
NewsAPI.ai is the commercial brand of Event Registry d.o.o., a Ljubljana company spun off from the Jožef Stefan Institute's AI lab in 2017. Instead of handing back a flat list of articles, it groups coverage of the same story across languages into events and tags each article with concepts, categories and sentiment. Pricing is published and token-based. A search over recent news costs one token, older archive queries cost more, and the 5K-token plan is listed at about $90 a month. Startup directories name Bloomberg, Nasdaq and IBM among its customers (per company materials; independently unverifiable).
Mediastack
Mediastack is one of the apilayer products, alongside ipstack and weatherstack. apilayer was founded in Vienna in 2015 by Julian and Paul Zehetmayr and acquired by the US software group Idera in January 2021. The API aggregates live and historical news from 7,500+ sources in 13 languages, filtered by country, category, language and keyword. The free plan allows 100 requests a month, and paid plans run from $24.99 for 10,000 requests to $249.99 for 250,000. Its source list is far smaller than the big crawlers here, and it adds no enrichment beyond basic metadata.
