GDELT Project vs Quantexa News API (Aylien): 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.
Quantexa News API (Aylien)
Aylien was founded in Dublin in 2012 and built one of the more advanced NLP news APIs, pulling multilingual content from roughly 80,000 sources and tagging it with entities, categories and sentiment. Quantexa, the London decision-intelligence company, acquired Aylien in February 2023 for an undisclosed sum, and the product now goes by Quantexa News Intelligence and Quantexa News API. Quantexa's community forum still advertises a 14-day trial. A competitor, however, reports that new subscribers are being pointed to a customer notice, and Quantexa has published no roadmap for the standalone API.
