NewsAPI.ai (Event Registry) vs Guardian Open Platform: overview
NewsAPI.ai (Event Registry)
NewsAPI.ai is sold by Event Registry d.o.o., a Ljubljana company that left the Jožef Stefan Institute's AI lab as a spin-off in 2017. Its query model is built around events: articles about the same real-world story in different languages are linked into one event record, and each article carries concepts mapped to Wikipedia entities, categories and sentiment. Developers get an open-source Python client on GitHub and a published token price list, with recent-news searches at one token and archive searches costing more; the 5K-token plan is about $90 a month. Expect to write paging code. A search returns at most 100 articles, so bigger pulls take many calls, each billed in tokens, and some developers report pagination and rate-limit friction on larger jobs (user reports; independently unverifiable).
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.
