# GetCanDelegatedMaxSize

In Stake2.0, query the amount of delegatable resources share of the specified resource type for an address, unit is sun.

This method will use `30` [Compute Units](https://docs.validationcloud.io/v1/about/billing).

***

## **Parameters**

* `owner_address` - String, required - Owner address, default hexString
* `type` - int32 - Resource type, 0 is bandwidth, 1 is energy
* `visible` - Boolean - Optional. Specifies whether the address is in Base58 format (default: false).

## **Returns**

`max_size` - int64 : the amount of delegatable resource share, unit is sun.

* When querying the delegatable energy share of an account, if the available energy share in the account is 0, this API returns {}
* When querying the delegatable bandwidth share of an account, if the bandwidth obtained by staking in the account is not enough to pay for the bandwidth consumed by a resource delegation transaction itself, this API also returns {}

Note: If the delegating transaction has a memo, it would consume more bandwidth, therefore the actual delegatable share would be less than the return of this API.
