Problem Statement

Every connected device around the world comes with a unique Media Access Control address, or a   MAC address. A common task a network administrator may come across is being able to identify a network device's manufacturer when given only a MAC address.

Interface with one (or numerous) APIs that exist on the internet and retrieve the device manufacturer based on a supplied MAC address. A MAC address that does not return a valid result should return the String "N/A".   An error related to the network connectivity or the API should return a null result. Many implementations on this page use http://api.macvendors.com/ which, as of 19th September 2021, is throttling requests. After only 2 calls, the following response is returned for all subsequent requests. If you are planning to use the same provider or going to run the examples on this page, consider building in a delay between two calls. {"errors":{"detail":"Too Many Requests","message":"Please slow down your requests or upgrade your plan at https://macvendors.com"}}

Let's start with the solution:

set apiRoot to "https://api.macvendors.com"
set macList to {"88:53:2E:67:07:BE", "D4:F4:6F:C9:EF:8D", ¬
                "FC:FB:FB:01:FA:21", "4c:72:b9:56:fe:bc", "00-14-22-01-23-45"}

on lookupVendor(macAddr)
  global apiRoot
  return do shell script "curl " & apiRoot & "/" & macAddr
end lookupVendor

set table to { lookupVendor(first item of macList) }
repeat with burger in macList's items 2 thru -1
    delay 1.5
    set end of table to lookupVendor(burger)
end repeat

set text item delimiters to linefeed
return table as string


set savedTID to text item delimiters
set text item delimiters to linefeed
set tableText to table as string
set text item delimiters to savedTID
return tableText
