Webz.io vs Diffbot: overview
Webz.io
Webz.io was founded in 2014 as Webhose.io and is run from the Tel Aviv area by co-founder and CEO Ran Geva. Its News API claims 3.5 million new articles a day from 350,000+ sources in 170+ languages (per company website; independently unverifiable), and the same token can query blogs, forums, reviews and dark-web feeds. For developers it is powerful but not quick to learn: queries use a field syntax (title:, language:, sentiment:) and anything older than 30 days goes through a separate archive endpoint that reaches 2008. Each account gets $5 of free credit a month and SDKs for Python, Node and Java. The default rate limit of one request per second is the thing to plan around.
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.
