Tavily vs Quantexa News API (Aylien): overview
Tavily
Tavily, founded by CEO Rotem Weiss, sells a search API designed for LLM agents. Its topic=news mode limits results to recent news and returns extracted text that can go straight into a prompt. Nebius, the Nasdaq-listed AI cloud company, agreed to buy Tavily in February 2026 (Bloomberg reported a $275 million price) and later said the deal had closed, with the Tavily brand and pricing kept in place. Billing runs on credits: one per basic search, two per advanced search, about $0.008 each on pay-as-you-go, and 1,000 free credits a month. As a search tool it has no news archive, source taxonomy or clustering.
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.
