Quantexa News API (Aylien) vs Marketaux: overview
Quantexa News API (Aylien)
Aylien was founded in Dublin in 2012 and built one of the more advanced NLP news APIs, pulling multilingual content from roughly 80,000 sources and tagging it with entities, categories and sentiment. Quantexa, the London decision-intelligence company, acquired Aylien in February 2023 for an undisclosed sum, and the product now goes by Quantexa News Intelligence and Quantexa News API. Quantexa's community forum still advertises a 14-day trial. A competitor, however, reports that new subscribers are being pointed to a customer notice, and Quantexa has published no roadmap for the standalone API.
Marketaux
Marketaux covers stock, crypto and forex news and tags each article with the tickers and entities it mentions, each scored for sentiment between -1 and 1. 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 at three articles per request, and the official pricing page lists Basic at $29 a month for 2,500 daily requests. Entity statistics and trending endpoints need a paid tier, and the site does not say who operates it or where.
