Can we get the source code files tree structure by one api call?

[Crag]

Hi atlassian team:

our team want to use the bitbucket rest api to get our repo's file/folder structure and return this as a json, do we have one call to send the condition in request and get the folder tree back in only one call, ex:  request: { folder: A }, response: {A:{B:{C:{....}}}}? otherwise, we have to call multi times to get this back with low performance.

the structure like this:

a {

b {

c {

file1

file2

}

}

b1 {

c1 {

file1

file2

}

}

}
