How this service works
Probability time series for a market with key-move detection — Hourly or daily blended probability series (per-venue series included where listed) with volume, plus key_moves: buckets where the blend moved at least 5 points. Useful for charting and for change-point context before paying for realtime reads.
Output
A time series of blended probability values (hourly or daily), optional per-venue series, volume at each timestamp, and a key_moves array listing time buckets where the blended probability changed by at least 5 percentage points — useful for charting and identifying inflection points.
