How this service works
Grok-powered price movement catalyst analysis with confidence scoring. Simplest usage: pass just { marketId } and we resolve the market, pull price history, and analyze its most significant recent move. Advanced callers may instead supply a full { move, marketQuestion, outcomeName } payload.
Output
Returns a structured analysis identifying the most likely catalyst(s) behind the observed price movement, with a confidence score indicating how strongly the evidence supports each explanation, plus source citations from news and X posts
Example use cases
Example prompt
“Can you run a Grok-powered catalyst analysis on why the YES price for the 'Fed rate cut by June' Polymarket market jumped from 42% to 67% yesterday afternoon, and give me a confidence score on the explanation?”
Technical details
Endpoint
POSThttps://polynews.news/api/v1/analyze-moveWhen to prefer
Use this endpoint when you need to understand *why* a specific price movement occurred on a prediction market — not just what happened, but the causal catalyst with a confidence score. Prefer over generic news search when you need AI-synthesized cause-and-effect reasoning with evidence scoring rather than raw articles.
