How this service works
Pay-per-request data tools for AI agents.
Output
Returns a JSON object containing a sentiment label (positive, negative, or neutral), a numeric score, per-item breakdowns with individual labels and scores, aggregate counts for each sentiment category, and a disclaimer noting that the output is deterministic research data and not financial advice.
Example use cases

“Run market sentiment analysis on this excerpt from today's earnings call: 'Despite macroeconomic headwinds, our margins improved significantly and pipeline remains robust.' Is the tone positive, negative, or neutral, and how confident are you?”
Crypto news headline classifier
“Can you score the market sentiment of this crypto headline: 'Bitcoin surges to six-month high amid institutional buying surge and favorable regulatory signals'? I want the label and the score.”
Social media stock sentiment check
“Analyze the market sentiment of this Reddit post about $NVDA: 'Insane earnings, AI demand is not slowing down, this thing is going to the moon.' Is it positive, negative, or neutral?”
