GDELT Project vs Marketaux: overview
GDELT Project
The GDELT Project, created by Kalev Leetaru, is an open research database that monitors broadcast, print and web news worldwide in more than 65 languages and publishes updates every 15 minutes. Its DOC 2.0 API searches recent coverage and returns article lists and timelines, while bulk event and knowledge-graph files can be queried in Google BigQuery. The main APIs are free and need no key. What you get back is metadata and links, so you still have to fetch and parse each page yourself.
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.
