NewsAPI.ai (Event Registry) vs Diffbot: overview
NewsAPI.ai (Event Registry)
NewsAPI.ai is sold by Event Registry d.o.o., a Ljubljana company that left the Jožef Stefan Institute's AI lab as a spin-off in 2017. Its query model is built around events: articles about the same real-world story in different languages are linked into one event record, and each article carries concepts mapped to Wikipedia entities, categories and sentiment. Developers get an open-source Python client on GitHub and a published token price list, with recent-news searches at one token and archive searches costing more; the 5K-token plan is about $90 a month. Expect to write paging code. A search returns at most 100 articles, so bigger pulls take many calls, each billed in tokens, and some developers report pagination and rate-limit friction on larger jobs (user reports; independently unverifiable).
Diffbot
Diffbot, founded by Mike Tung in 2008 and based in Menlo Park, California, has an estimated 30–40 staff. Point its Article API at any news URL and it returns title, author, date and clean text without a site-specific parser, and Crawlbot can follow a list of publishers you choose. Its Knowledge Graph links articles to companies, people and topics, so it can also be queried as a news source. The free plan includes 10,000 credits at five calls a minute, Startup costs $299 a month for 250,000 credits, and each exported Knowledge Graph entity costs 25 credits. It works best when you want to build your own news collection from chosen sites.
