GDELT Project vs Marketaux: overview
GDELT Project
The GDELT Project, created by Kalev Leetaru, watches broadcast, print and web news in more than 65 languages and publishes fresh data every 15 minutes. The DOC 2.0 API needs no key and no signup, which makes it the fastest free start here, and it returns article lists and timelines for a query. Bulk event and knowledge-graph tables are also available in Google BigQuery for SQL users. Two things trip developers up. Responses contain metadata and links only, so you have to fetch and parse each article yourself, and the data formats were designed for researchers, with field names and conventions that take some reading to understand.
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.
