NewsAPI.ai (Event Registry) vs Alpha Vantage News & Sentiment: 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).
Alpha Vantage News & Sentiment
Alpha Vantage was founded in Boston in 2017 by Olivier Porte and Steve Zheng and went through Y Combinator's Summer 2018 batch. Its NEWS_SENTIMENT function returns market news with an overall sentiment score plus per-ticker and per-topic scores, from the same key that serves prices, fundamentals and technical indicators. Many hobby trading projects start here because the free key arrives instantly. Third-party guides describe the free allowance as 25 requests a day at five a minute, and premium plans as starting at $49.99 a month for 75 requests a minute with no daily cap. Commercial use is a separate question, and one source reports commercial licences in the $499 to $2,499 a month range. Responses carry summaries and links; full articles live on the publishers' sites.
