Webz.io vs Massive (ex-Polygon.io) News: 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.

Massive (ex-Polygon.io) News

Massive is the name Polygon.io took on October 30, 2025. The company was founded in Atlanta around 2016 by Quinton Pike, and old api.polygon.io endpoints keep working beside the new api.massive.com base. Its ticker news endpoint returns recent articles for a symbol with summaries, publisher details and an insights array giving a sentiment label and a one-sentence reason for each ticker mentioned. Sentiment only exists for articles published after July 2, 2024. Ticker news is included in every Stocks plan: the free Basic tier reaches two years of history, and Stocks Starter costs $29 a month. Official SDKs cover Python, Go, JavaScript and more, and flat files can be pulled from S3.
