Updates
Authenticated update-monitoring methods for market volatility, update windows, and historical feed-change signals.
Updates API methods are built for monitoring Google Discover volatility by market. They provide the same signal family as the public Discover update pages, with authenticated access patterns for production monitoring and internal dashboards.
#Main methods
- Market volatility: current index, 30-day average, peak, and likely-update count.
- Historical series: daily or intraday volatility values for charting and alert history.
- Market comparison: compare volatility across countries available in D2TR.
- Update episodes: grouped windows where volatility crossed the update threshold.
#Public companion
For no-auth access to the public volatility model, use Discover signals. Paid Updates access uses the same conceptual model but is intended for larger polling volume and account-scoped workflows.
