Diffbot vs Quantexa News API (Aylien): overview
Diffbot
Diffbot, founded by Mike Tung in 2008 and based in Menlo Park, California, has an estimated 30–40 staff. Point its Article API at any news URL and it returns title, author, date and clean text without a site-specific parser, and Crawlbot can follow a list of publishers you choose. Its Knowledge Graph links articles to companies, people and topics, so it can also be queried as a news source. The free plan includes 10,000 credits at five calls a minute, Startup costs $299 a month for 250,000 credits, and each exported Knowledge Graph entity costs 25 credits. It works best when you want to build your own news collection from chosen sites.
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.
