This function always errors.

Details

The 'RESAS' API (https://opendata.resas-portal.go.jp/) was discontinued on 2025-03-24, and accounts as well as API keys were deleted. Therefore resas() no longer works and has been made defunct.

As an alternative for prefectural and municipal data, consider the MLIT Data Platform (DPF) GraphQL API (https://www.mlit-data.jp/).
