    DDS-18 mineral occurrences (~335). Filter commodity/group/deposit/status/pastProducerOnly/bbox.

    AK has NO county — use bbox or near. property_status: 4 values.

  • searchGeologicMaps

    read

    DGGS+USGS map publication index (~4.16K polygons). Filter agency/scale/title/keyword.

    agency: USGS or DGGS. publication_number prefix is the series code.

  • searchMineralDistricts

    read

    Alaska mining-district polygons (~75 across 14 regions). Filter name or region.

    region uses UPPER LIKE substring (catches a double-space upstream typo).

  • searchVolcanoes

    read

    AVO volcano inventory (~53). Filter name/identityConfidence/sinceYear/bbox/near.

    outFields=* triggers gateway error — handler uses explicit field list.

  • getServiceInfo

    read

    Schema + record counts + enum values for any of the 5 services. Pass `service` to scope.
