GET/api/v1/sigmets/by-areaPrivate Pilot

Search By Area

Finds SIGMETs that intersect a geographic bounding box. Returns advisories whose boundary overlaps the specified area, useful for checking conditions across a flight route.

Code Examples

curl \
  -H "Ocp-Apim-Subscription-Key: YOUR_API_KEY" \
  "https://api.preflightapi.io/api/v1/sigmets/by-area?minLat=40.0&maxLat=41.0&minLon=-74.5&maxLon=-73.0&limit=25"

Description

Note: The bounding box must not cross the antimeridian (i.e., minLon must be less than maxLon). Antimeridian-crossing queries are not supported. This endpoint covers domestic US SIGMETs within the contiguous United States.
