Also, I was looking at https://newsapi.org. How does your python API compare? I see that in newsapi, it also get old articles; do you implement similar features?
Newscatcher API is a product that allows you not only get the latest articles but also search by keywords, topic, country etc. Basically, the main feature is that you search for articles that contain a specific word or phrase. This can have an added value for professionals and companies. There will be a free plan for developers with limits and chargeable for more heavy usage.
Compare to newsapi, we are less expensive for the content. We will not be able to get old articles from today. We began to stock data couple at the release.
Hope I answered all of your questions.
