Marketaux vs Finnhub: overview
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.
Finnhub
Finnhub is a New York fintech founded in 2018, according to CB Insights, with staff reported in New York, Mumbai, Sydney and Ho Chi Minh City. It sells stock, forex and crypto data over REST and WebSocket, and news is one endpoint among many. The free key is generous on rate (60 calls a minute) and returns a year of North American company news plus general market headlines, but it is for personal, non-commercial use, and low-latency news streaming is a premium feature. Official SDKs cover Python, Go, JavaScript and more. Commercial bundles are priced on the site, with All-in-One listed at $1,000 a month.
