NewsAPI.ai (Event Registry) vs Tavily: overview
NewsAPI.ai (Event Registry)
NewsAPI.ai is the commercial brand of Event Registry d.o.o., a Ljubljana company spun off from the Jožef Stefan Institute's AI lab in 2017. Instead of handing back a flat list of articles, it groups coverage of the same story across languages into events and tags each article with concepts, categories and sentiment. Pricing is published and token-based. A search over recent news costs one token, older archive queries cost more, and the 5K-token plan is listed at about $90 a month. Startup directories name Bloomberg, Nasdaq and IBM among its customers (per company materials; independently unverifiable).
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.
