• Get count after LIMIT and OFFSET.
  GET: /bond/transfers/{token_address}
  GET: /bond/transfer_approvals/{token_address}
  GET: /share/transfers/{token_address}
  GET: /share/transfer_approvals/{token_address}
  e.g.) https://github.com/BoostryJP/ibet-Prime/blob/dev-21.12/app/routers/bond.py#L955
• Get count before LIMIT and OFFSET.
  GET: /files
  GET: /ledger/{token_address}/history
  GET: /ledger/{token_address}/details_data
  GET: /notifications
  e.g.) https://github.com/BoostryJP/ibet-Prime/blob/dev-21.12/app/routers/file.py#L87
• The count of get after is always less than or equal to LIMIT, but get before may be greater than or equal.
