Read-onlyIdempotent

Historical aggregates: VPD crime by year/month/type (6y), USGS M4+ quakes per region (10y), GDACS global events (3y), report and live snapshot stats. Use for questions about patterns over time — crime trends, quake frequency, disaster cadence. For what's happening right now, use get_incidents.
