What AlphaAI is
alphai's Stock News API is a REST service that delivers real-time financial news to trading bots, AI agents, and dashboards. Every item comes back in JSON with a relevance score from 1 to 10, plus sentiment analysis and written reasoning for each stock code. The same feed includes SEC EDGAR documents such as Form 4 insider trading filings, and 8-K and 6-K filings sorted into categories like earnings and mergers. Market-wide macro news and an economic calendar are included, repeated stories can be collapsed into one line, and cursor polling supports incremental reads. A free plan allows 100 requests per day and 20 per minute with no credit card, while paid tiers cost $2.99 and $9.99 per month.

What to watch out for
The free plan is capped at 100 requests per day and 20 per minute, which is fine for testing but tight for busy systems, and these limits can change. News and sentiment data are inputs, not advice, and any automated trading still needs its own risk controls, because a misread filing or a bad score can cost real money. Check the licensing terms before you redistribute the data. For best results, start with a small test file and review the output carefully before working on anything important.
