Exa vs Marketaux: overview
Exa
Exa Labs was founded in 2021 in San Francisco by Will Bryk and Jeff Wang under the name Metaphor, and raised an $85 million Series B led by Benchmark in September 2025. It runs its own embeddings-based web index. A request can be narrowed to the news category and can return cleaned page contents in the same call. As of 2026 the Search endpoint is listed at $7 per 1,000 requests with contents for the first 10 results included, and new accounts get $20 in credit. Exa is a general web search engine first, so small regional outlets and strict publication-date filters are weaker spots than in dedicated news APIs.
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.
