Quantexa News API (Aylien) vs Guardian Open Platform: overview
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.
Guardian Open Platform
The Guardian's Open Platform gives developers the same content API that runs the Guardian's own sites, with full article bodies, tags and sections going back to 1999. A free developer key is commonly reported at about 5,000 calls a day and 12 calls a second, and it is meant for non-commercial projects. Commercial use needs a separate agreement with Guardian News & Media. Clean, consistent tagging has made it a favourite for teaching and research, though you only ever get one publisher.
