Looping API Call, restrict results

Hi,

 

I have the following looping API call in PowerBI desktop, is there anything I can add/change so that it loops for say only the first 1000 records (10 pages) instead of returning all records?

 

let
ufnQuery = (n) =>
let
jsonDoc= Json.Document(
Web.Contents(
"[replace this with web address]/?&start=" & Number.ToText(n))),
result = jsonDoc[result],
records = result[records],
tmpTbl = Table.FromList(records, Splitter.SplitByNothing(), null, null, ExtraValues.Error)
in
tmpTbl,

fnRecursive = (tbl, n) =>
if Table.RowCount(ufnQuery(n)) > 0 then @fnRecursive(Table.Combine({tbl, ufnQuery(n)}), n+100) else tbl,

tbl = ufnQuery(0),
final = fnRecursive(tbl ,100),
#"Expanded Column1" = Table.ExpandRecordColumn(final, "Column1", {"id", "start", "answer", "end", "src", "dst", "from_number", "to_number", "from_name", "to_name", "billsec", "disposition", "lastapp", "userfield", "faxdata", "lastdata", "cost", "organization", "channel", "dstchannel", "app", "callclass", "dest_type", "duration", "dcontext", "pbxid", "type", "timezone"}, {"id", "start", "answer", "end", "src", "dst", "from_number", "to_number", "from_name", "to_name", "billsec", "disposition", "lastapp", "userfield", "faxdata", "lastdata", "cost", "organization", "channel", "dstchannel", "app", "callclass", "dest_type", "duration", "dcontext", "pbxid", "type", "timezone"})
in
#"Expanded Column1"
