Is there an API to know if a number is registered with WhatsApp or not?

Preferably "without SMS and registration", and other dances.
checkwa.online wants money.

Legally - only through the WhatsApp Business API, which is not free.
But you can find out through the Web client. And already try to attach crutches to him, risking getting a ban from WA.

Didn't find what you were looking for?
