Exa vs Marketaux: overview
Exa
Exa Labs started in San Francisco in 2021 as Metaphor, founded by Will Bryk and Jeff Wang, and raised an $85 million Series B led by Benchmark in September 2025. It runs its own web index searched by meaning, so a query like "startups cutting cloud costs" can match articles that never use those words. Set the category to news and ask for contents, and one request returns cleaned text you can drop into a prompt. As of 2026 search costs $7 per 1,000 requests with contents for the top 10 results included, and new accounts start with $20 of credit. SDKs cover Python and TypeScript, and an official MCP server plugs it into agent tools. It is a search engine at heart, so expect weaker coverage of small regional outlets and fuzzier publication dates than a dedicated news API gives.
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.
