NewsAPI.ai (Event Registry) vs Marketaux: 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).
Marketaux
Marketaux saves fintech developers from writing a ticker matcher. Every stock, crypto or forex article it returns lists the entities it mentions, each with a sentiment score from -1 to 1, and that works on the free plan too. Listings put coverage at about 5,000 sources in 30+ languages and 200,000+ tracked entities (per company website; independently unverifiable). The free plan allows 100 requests a day but returns only three articles per request. The official pricing page lists Basic at $29 a month for 2,500 daily requests, and entity statistics and trending endpoints need a paid plan. The site does not say who operates it or where.
