💰 Pricing

This Actor uses Pay-Per-Event. The primary event is number-checked, billed once per number validated. You also pay standard Apify platform usage (compute). Bulk runs are efficient — you only pay for the numbers you check.

❓ FAQ

Do I need a WhatsApp account or API key? No. It works out of the box.

Does it message the number? No. Validation is passive — the target person is never contacted or notified.

Why did a number come back as an error? Transient network/engine hiccups can cause an occasional error status. Re-run those numbers — the Actor always returns the successful ones regardless.

Can I check thousands of numbers? Yes. Add them all to phoneNumbers. Results stream in live as they complete.
