Massive (ex-Polygon.io) News vs Currents API: overview
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.
Currents API
Currents API has run since about 2018 with latest-news and search endpoints filtered by language, region and category. Developer roundups often point beginners to its free tier, but they quote the limit as 600 requests a day, 600 a month or 250 a day depending on the article, and the free plan returns latest news only, with no historical search or commercial use. One report lists paid plans from $69 a month for 75,000 requests (independently unverifiable). The operator, location and team are not published.
