Retrieve a controller by id

This endpoint retrieves a specific controller by its unique identifier (Id).

Controllers on the TEOS platform are blockchain-level entities that define restrictions and permissions for specific operations with blockchain data types.

A controller may include whitelisted and blacklisted addresses, which determine which wallets or users can interact with the associated assets. This endpoint returns full details of a controller, including its metadata and address lists, by providing its unique ID.
