Tavily vs Alpha Vantage News & Sentiment: overview
Tavily
Tavily, founded by CEO Rotem Weiss, is a search API designed to be called by LLM agents, and its topic=news mode limits results to recent coverage with extracted text ready for a prompt. It is the quickest way on this list to give a LangChain or LlamaIndex agent a news tool, since both frameworks ship Tavily integrations. Nebius, the Nasdaq-listed AI cloud company, agreed to buy Tavily in February 2026 (Bloomberg put the price at $275 million) and later said the deal had closed, keeping the brand and pricing. Credits cost about $0.008 each on pay-as-you-go, a basic search uses one and an advanced search two, and 1,000 credits a month are free. Because it is a search tool, there is no archive, source list or clustering to work with.
Alpha Vantage News & Sentiment
Alpha Vantage was founded in Boston in 2017 by Olivier Porte and Steve Zheng and went through Y Combinator's Summer 2018 batch. Its NEWS_SENTIMENT function returns market news with an overall sentiment score plus per-ticker and per-topic scores, from the same key that serves prices, fundamentals and technical indicators. Many hobby trading projects start here because the free key arrives instantly. Third-party guides describe the free allowance as 25 requests a day at five a minute, and premium plans as starting at $49.99 a month for 75 requests a minute with no daily cap. Commercial use is a separate question, and one source reports commercial licences in the $499 to $2,499 a month range. Responses carry summaries and links; full articles live on the publishers' sites.
