NewsData.io vs Alpha Vantage News & Sentiment: 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.
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.
