WhatsApp number verify without WA business API. Possible?

Hi all,
Anyone know of a way to verify if a specific number is a registered on WhatsApp, without using the WhatsApp business API?

We do have an business account on WA but they clearly state the “too many” requests to verify number will likely cause the account to be banned.

If you check too many phone numbers without sending messages to them, you will be banned.

The wa.me/[number] doesn’t return anything we can capture. Or does it?
I’m not asking about a way to send a message. Just to verify if number is on WhatsApp.

Yes, you can try proweblook.com they are offering api to check whatsapp number
