Get climate-event indices for any location over a date range within the rolling ~5-year ERA5 window (reanalysis): frost and summer days, tropical nights, dry spells, heavy-rain days, max one-day rainfall, total precipitation and peak gust — parametric-insurance triggers computed from true daily Tmin/Tmax, decoded from GRIB. Also accepts city=<name> (alias location=, optional country= ISO 3166 alpha-2) instead of lat/lon, resolved via the embedded GeoNames gazetteer (exact match, most populous wins) and echoed back as data.location. No account, no key, pay per call.
