Resolve a Hawaii street address (or a TMK) to a Tax Map Key (TMK) parcel id. Geocodes the address (HI-bounded Nominatim) then finds the parcel under it. Use this first when you only have an address; feed the TMK into lookup_parcel.

Look up the full Āina Atlas parcel record for a Hawaii property by address or TMK. Returns the real structured JSON: TMK, island, acres, owner, zoning, land/building value, hazards (lava zone, tsunami evacuation, FEMA flood), Hawaiian context (ahupuaʻa / moku / mokupuni), slope & solar exposure, native plants, ADU eligibility, AVM, tax-appeal window, and deep links. This is the core lookup and needs no API key.

Compare two Hawaii parcels side by side. Each input may be an address or a TMK. Returns both full parcel records plus a compact diff of key fields (acres, zoning, values, hazards, ADU).
