Massive (ex-Polygon.io) News vs Quantexa News API (Aylien): overview
Massive (ex-Polygon.io) News
Massive is the name Polygon.io took on October 30, 2025. The company was founded in Atlanta around 2016 by Quinton Pike, and old api.polygon.io endpoints keep working beside the new api.massive.com base. Its ticker news endpoint returns recent articles for a symbol with summaries, publisher details and an insights array giving a sentiment label and a one-sentence reason for each ticker mentioned. Sentiment only exists for articles published after July 2, 2024. Ticker news is included in every Stocks plan: the free Basic tier reaches two years of history, and Stocks Starter costs $29 a month. Official SDKs cover Python, Go, JavaScript and more, and flat files can be pulled from S3.
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.
