GDELT Project vs Quantexa News API (Aylien): 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.
Quantexa News API (Aylien)
Aylien, founded in Dublin in 2012, built a well-regarded NLP news API that tagged multilingual articles from about 80,000 sources with entities, categories and sentiment, and shipped Python and Node SDKs. Quantexa, the London decision-intelligence company, bought it in February 2023 for an undisclosed sum, and the product is now called Quantexa News Intelligence or Quantexa News API. Quantexa's community forum still advertises a 14-day trial, but a competitor reports that new sign-ups are directed to a customer notice, and there is no public roadmap for the standalone API. It makes most sense for existing users and Quantexa customers, and a new build is safer elsewhere.
