1Request

geometryobjectRequired

GeoJSON (RFC 7946, WGS84, [lon, lat]) Point, Polygon or MultiPolygon, or a Feature wrapping one. Rings must be closed; altitude is ignored. A FeatureCollection is refused (send one place per call), as is a geometry crossing the antimeridian. Invalid input is `invalid_input` with a JSON pointer and a stable code (ring_not_closed, latitude, longitude, too_large, too_many_vertices, outside_coverage).

buffer kmnumber

Also keep storm-based alerts whose polygon lies within this many kilometres of the geometry, and resolve zones for points this far outside its bounding box.

eventsstring[]

Keep only these event names (case-insensitive substring match on the NWS event name, e.g. "Red Flag", "Flood", "Heat"). Separate values with commas.

severitystring[]

Keep only alerts with one of these CAP severities. Separate values with commas.
