Get all cells within k hops (kRing / grid disk)

GET 
/v2/hexcode/:code/disk

Returns all hex cells within k hops of the origin cell. This is the H3 "grid disk" operation (formerly kRing). Useful for proximity searches, collection route clustering, and hex-native geofencing.

Cell count follows the formula 3k² + 3k + 1: k=0 → 1, k=1 → 7, k=2 → 19, k=3 → 37, k=5 → 91, k=10 → 331.
