NewsAPI.ai (Event Registry) vs Guardian Open Platform: 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).
Guardian Open Platform
The Guardian's Open Platform gives developers the same content API that runs the Guardian's own sites, with full article bodies, tags and sections going back to 1999. A free developer key is commonly reported at about 5,000 calls a day and 12 calls a second, and it is meant for non-commercial projects. Commercial use needs a separate agreement with Guardian News & Media. Clean, consistent tagging has made it a favourite for teaching and research, though you only ever get one publisher.
