Finnhub vs Quantexa News API (Aylien): overview
Finnhub
Finnhub is a New York fintech founded in 2018, according to CB Insights, with staff reported in New York, Mumbai, Sydney and Ho Chi Minh City. It sells stock, forex and crypto data over REST and WebSocket, and news is one endpoint among many. The free key is generous on rate (60 calls a minute) and returns a year of North American company news plus general market headlines, but it is for personal, non-commercial use, and low-latency news streaming is a premium feature. Official SDKs cover Python, Go, JavaScript and more. Commercial bundles are priced on the site, with All-in-One listed at $1,000 a month.
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.
