Answer 1

You can use this sample through HttpClient. Additionally, you can use Microsoft.TeamFoundationServer.Client and BuildHttpClient.GetBuildsAsync: the example is here.

Answer 2

There are 2 ways to do authentication for Azure DevOps API.
Private PAT
Environment Variable: System.AccessToken
For PAT you can review Shamrai Aleksander's code, if you want to call Azure DevOps API in your pipeline, you can conside use System.AccessToken.
Here is Powershell Script for your reference, the field of Authorization is different.
function Http-Request {
param (
[Parameter(Mandatory=$true)]
[string] $Url,
[Parameter(Mandatory=$false)]
[string] $SystemToken
)
if([string]::IsNullOrEmpty($SystemToken)) {
$pat = 'YOUR_PAT'
$username = 'YOUR_USERNAME'
$auth = '{0}:{1}' -f $username, $pat
$bytes = [System.Text.Encoding]::UTF8.GetBytes($auth)
$encoded = [Convert]::ToBase64String($bytes)
$auth = 'Basic ' + $encoded
} else {
$auth = 'Bearer ' + $SystemToken
}
$headers = #{
'Content-Type' = 'application/json'
'Authorization' = $auth
}
Write-Host -ForegroundColor Green 'Http Request:'$Url
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls -bor [Net.SecurityProtocolType]::Tls11 -bor [Net.SecurityProtocolType]::Tls12
$response = Invoke-RestMethod -Uri $Url -Method Get -Headers $headers
Write-Host ($reponse | Format-List | Out-String)
return $response
}
