NewsCatcher vs Diffbot: overview
NewsCatcher
Most news APIs hand you raw articles and leave the cleanup to you. NewsCatcher, a Y Combinator Summer 2022 company founded by Artem Bugara and Maksym Sugonyaka (registered in Delaware, team mostly in Europe), does that cleanup on its side: articles come back summarised, deduplicated, clustered into stories and tagged with entities. Version 3 of the API covers 140,000+ sources in 50+ languages with more than 2 billion articles since 2019 (per company website; independently unverifiable), and a separate Local News endpoint adds a location and a confidence score to each story. Official SDKs exist for Python, Node and Java, and the company reports SOC 2 Type II and a 99.95% uptime SLA. The catch for a solo developer is price discovery: there is a pay-as-you-go trial, but production plans are quoted by sales.
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.
