MAC vendor lookup
You are encouraged to solve this task according to the task description, using any language you may know.
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.
- Task
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"}}

Normally something like this would just be mapping the lookup across an array, but that doesn't let us control the timing of the request dispatch. To insert a delay between requests we have to create a traditional function ("tradfn") with a for loop.
⍝load the library module
]load HttpCommand
⍝ define a direct function (dfn) to look up a single MAC address
vendorLookup1 ← { (HttpCommand.Get 'http://api.macvendors.com/',⍕⍵).Data }
⍝ define a traditional function to look up all the MAC addresses in a list with
⍝ a delay between calls
⍝ The header says that the function is named vendorLookup, it takes a single
⍝ parameter which we call macList, and the value of the local variable
⍝ vendors will become the function's return value
∇ vendors ← vendorLookup macList
⍝ look up the first vendor and put it into an array in our return var
vendors ← ⊆vendorLookup1 1↑macList
⍝ Loop over the rest of the array
:For burger :In 1↓macList
⎕DL 2 ⍝ wait 2 seconds
vendors ⍪← ⊆vendorLookup1 burger ⍝ then look up the next vendor and append
:EndFor
∇
⍝ demo data
macList ← '88:53:2E:67:07:BE' 'D4:F4:6F:C9:EF:8D' 'FC:FB:FB:01:FA:21'
macList ⍪← '4c:72:b9:56:fe:bc' '00-14-22-01-23-45'
⍝ look up the vendors (takes a while with the 2-second delay between lookups)
vendorList ← vendorLookup macList
⍝ the result is an array (a 1-row by N-column matrix). to print out one vendor
⍝ per line, we reshape it to be N rows by 1 column instead.

set end of table to lookupVendor(burger)

If this is part of a larger script you probably want to save and restore the text item delimiters:

set text item delimiters to linefeed
