NewsData.io vs Massive (ex-Polygon.io) News: overview

NewsData.io

NewsData.io, operated from Noida, India, is the API on this list that most developers can get running in a lunch break. Signup gives a key immediately, the free plan refills 200 credits every day (each credit returns up to 10 articles), and the query parameters are plain enough that a first working request needs no SDK, although an official Python client exists. Coverage is claimed at 99,000+ sources in 206 countries and 89 languages (per company website; independently unverifiable). The free plan only looks back 48 hours and delays streamed data by 12 hours. Paid plans start at $199.99 a month for 20,000 credits and six months of history and go up to $1,299.99 for 1 million credits and 10 years. Public profiles disagree on the founding year: LinkedIn says 2022, some directories say 2019.

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.
