Check a phone number before you message it on WhatsApp. One request returns validity, line type, carrier, location, WhatsApp registration, and business-account detection. For list cleaning and campaigns. Send an E.164 number to GET /wavalidation. 20 free requests per application, then $0.003 each, or $9.99/month for 5,000 and $29.99/month for 30,000. Try 5 live checks per IP a day.

Hey Product Hunt — I built this because messaging a number that is not on WhatsApp wastes the send and can drag down a WhatsApp Business account.
It is one GET. Pass a phone number in E.164 format:
curl --request GET 'https://gateway.payloadapi.com/whatsapp-validation/v1/wavalidation?phone_number=+14155552671' --header "Authorization: Bearer $PAYLOADAPI_KEY"
You get back whether the number is valid, the line type, the carrier, the location, whether it is registered on WhatsApp, and whether that account is a business account.
You can try it on the page before creating a key: 5 live checks per IP every 24 hours. A free application includes 20 requests. After that it is $0.003 per request, or $9.99/month for 5,000 requests, or $29.99/month for 30,000.
This is the first API we are launching on its own. One API per week from here.
If you clean phone lists or run WhatsApp outreach, tell me what is missing from the response. I will be here in the comments.
