Guardian Open Platform vs Quantexa News API (Aylien): overview
Guardian Open Platform
The Guardian's Open Platform exposes the same content API that powers the Guardian's websites and apps. A free developer key returns full article bodies with tags and sections back to 1999, and commonly reported limits are about 5,000 calls a day and 12 a second. The key is for non-commercial projects; commercial use needs a deal with Guardian News & Media. Developers like it for teaching because the tagging is consistent and the responses are predictable, which makes it a good dataset for NLP exercises. The obvious limit is that every article comes from one newspaper.
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.
