Serper Google News vs Marketaux: overview
Serper Google News
Serper is a Google search API that many agent frameworks list as a default search tool, and it can return Google News results as well as web results. Signup needs no card and comes with 2,500 free queries, which third-party write-ups describe as a one-time allowance. Billing is in prepaid credits: one credit for up to 10 results, two for up to 100. A third-party pricing breakdown lists packs from $50 for 50,000 credits, valid for six months, and one report says the public pricing page was offline in mid-2026, so check the figures in your account. The company behind it publishes little about itself, and like any Google-scraping API it returns titles, snippets and links instead of article text.
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.
