Can I make an api call to pull the games from all my matches vs stockfish level 8

I know the lichess api lets me pull my games in bulk but is there a way to make sure the ones I play vs the lichess engine from start of game or from a specific Fen is included in that api request?

*as per lichess.org/api#operation/apiGamesUser

*it shows up in the pgn games as opponent name "lichess AI level 8" when doing without filter
works for the game you played against me: lichess.org/api/games/user/fishbrah?vs=MrN0b0dy227

I not sure if issue is due to spaces in name or something non-existant for it being an actual user principal

I had to read up on tools.ietf.org/html/rfc3986 but this looks right. Not sure why but it appears that the stock fish AI is immune to selection via ?vs= query string

best I can think of ATM is a File.ReadAllLines("download.pgn").ToList().ForEach(line=>{Regex.Replace(line, "regex", "");} ); and then write that to a file.
