Diffbot vs APITube: overview
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.
APITube
APITube advertises filters for language, country, category, sentiment and entities, and posts regular developer tutorials on Medium and DEV. Aggregator listings put its coverage somewhere between 300,000 and 500,000 sources in about 60 languages (per company materials; independently unverifiable). The company behind it is not named beyond a developer profile located in Texas, and no founding date is published. Its own site shows paid plans, but third-party listings quote different figures. Run your real queries through the free tier and compare results with another provider before you depend on it.
