    Hello @pwares

    The token must be provided in the request header. I tried this and it works, just enter your own token at the top. Sample PBIX file here.

    let
    
    api_url = "https://www.ncdc.noaa.gov/cdo-web/api/v2/datasets?stationid=GHCND:USW00014732&stationid=GHCND:USW00013739&stationid=GHCND:USW00014739&stationid=GHCND:USW00094823&stationid=GHCND:USW00014765",
        token = "XXXXXXXXX",
    
    Source = Json.Document(Web.Contents(api_url,
       [ 
         Headers = [token = token ,#"Content-Type"="application/json"]
       ]
       )
       ),
        #"Converted to Table" = Record.ToTable(Source),
        Value = #"Converted to Table"{1}[Value],
        #"Converted to Table1" = Table.FromList(Value, Splitter.SplitByNothing(), null, null, ExtraValues.Error),
        #"Expanded Column1" = Table.ExpandRecordColumn(#"Converted to Table1", "Column1", {"uid", "mindate", "maxdate", "name", "datacoverage", "id"}, {"uid", "mindate", "maxdate", "name", "datacoverage", "id"})
    in
        #"Expanded Column1"

    Best regards
