NewsData.io vs Marketaux: overview
NewsData.io
NewsData.io, operated from Noida, India, is the API on this list that most developers can get running in a lunch break. Signup gives a key immediately, the free plan refills 200 credits every day (each credit returns up to 10 articles), and the query parameters are plain enough that a first working request needs no SDK, although an official Python client exists. Coverage is claimed at 99,000+ sources in 206 countries and 89 languages (per company website; independently unverifiable). The free plan only looks back 48 hours and delays streamed data by 12 hours. Paid plans start at $199.99 a month for 20,000 credits and six months of history and go up to $1,299.99 for 1 million credits and 10 years. Public profiles disagree on the founding year: LinkedIn says 2022, some directories say 2019.
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.
