Hi Everyone,

I'm very new to chess.com but quite addicted already and was stoked to discover this API !! Only just found it a few hours ago but knocked up a little Powershell (my preferred language) and thought I'd share (since nobody else I know "in real life" will appreciate it)...

Clear-Host

$myUser = Read-Host "Your chess.com username"
$opponent = Read-Host "Opponent's username (leave blank for all opponents)"
if (!$opponent) { $opponent = ".*"}

$myArchives = Invoke-WebRequest -Uri https://api.chess.com/pub/player/$myUser/games/archives | ConvertFrom-Json

$games = @()
foreach ($archive in $myArchives.archives) {
 $games += Invoke-WebRequest -Uri $archive | select -ExpandProperty content | ConvertFrom-Json
}

$results = $games.games | select white,black

$whiteWins = 0
$whiteLosses = 0
$whiteDraws = 0
$whiteAbandons = 0
$blackWins = 0
$blackLosses = 0
$blackDraws = 0
$blackAbandons = 0

foreach ($row in $results) {

 if (($row | select -ExpandProperty white | select -ExpandProperty username) -eq $myUser `
 -and ($row | select -ExpandProperty black | select -ExpandProperty username) -match $opponent) {

 switch (($row | select -ExpandProperty white | select -ExpandProperty result)) {

 "win" { $whiteWins += 1}
 "checkmated" { $whiteLosses += 1}
 "resigned" { $whiteLosses += 1}
 "agreed" { $whiteDraws += 1}
 "abandoned" { $whiteAbandons += 1}
 "timeout" { $whiteLosses += 1}
 }

 } 
 
 if (($row | select -ExpandProperty black | select -ExpandProperty username) -eq $myUser `
 -and ($row | select -ExpandProperty white | select -ExpandProperty username) -match $opponent) {

 switch (($row | select -ExpandProperty black | select -ExpandProperty result)) {

 "win" { $blackWins += 1}
 "checkmated" { $blackLosses += 1}
 "resigned" { $blackLosses += 1}
 "agreed" { $blackDraws += 1}
 "abandoned" { $blackAbandons += 1}
 }

 }

}

Write-Host "`n$myUser playing as White...
Wins: $whiteWins
Losses: $whiteLosses
Draws: $whiteDraws
Abandoned: $whiteAbandons"

Write-Host "`n$myUser playing as Black...
Wins: $blackWins
Losses: $blackLosses
Draws: $blackDraws
Abandoned: $blackAbandons"

Write-Host "`n$myUser Totals...
Wins: $($blackWins + $whiteWins)
Losses: $($blackLosses + $whiteLosses)
Draws: $($blackDraws + $whiteDraws)
Abandoned: $($blackAbandons + $whiteAbandons)"

Thanks. Powershell is not something I've tried (Windows is for running PGN Spy ... only!? ) but have discussed Powershell with someone I respect who's done good stuff (not related to chess) with it. Thanks for giving us another example of accessing api.chess.com from a different language.

I believe Windows is quite widely used, so this may be helpful to others.
