Look up the zoning polygon that intersects a point. Returns the smallest matching polygon at the given coordinate to prefer the most specific classification. Available for 10 cities — see Municipal Intelligence Coverage for the full city list.

If no polygon directly intersects the coordinate — for example, when a point falls on a road boundary or gap between zones — the API returns the nearest polygon within 150 metres. If nothing is found within 150 metres, the endpoint returns 404.
