Alpha Vantage News & Sentiment vs Quantexa News API (Aylien): overview
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.
Quantexa News API (Aylien)
Aylien, founded in Dublin in 2012, built a well-regarded NLP news API that tagged multilingual articles from about 80,000 sources with entities, categories and sentiment, and shipped Python and Node SDKs. Quantexa, the London decision-intelligence company, bought it in February 2023 for an undisclosed sum, and the product is now called Quantexa News Intelligence or Quantexa News API. Quantexa's community forum still advertises a 14-day trial, but a competitor reports that new sign-ups are directed to a customer notice, and there is no public roadmap for the standalone API. It makes most sense for existing users and Quantexa customers, and a new build is safer elsewhere.
