Tavily vs Marketaux: 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.
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.
