Tavily vs Marketaux: 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.

Marketaux

Marketaux saves fintech developers from writing a ticker matcher. Every stock, crypto or forex article it returns lists the entities it mentions, each with a sentiment score from -1 to 1, and that works on the free plan too. 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 but returns only three articles per request. The official pricing page lists Basic at $29 a month for 2,500 daily requests, and entity statistics and trending endpoints need a paid plan. The site does not say who operates it or where.
