Workflow
How it works
The customer journey stays short whether a user is checking a single number in the web app or calling the API directly.
Create an account
Users register, receive a JWT session for the web app, and manage their profile and API keys from the same product.
Run a check
The validator pre-deducts credits, calls the upstream checker, and automatically refunds when the result is undetermined or fails.
Review usage
Dashboard statistics, 7-day product trends, and validation history help teams understand where credits are going.
Questions and answers
Everything you need before your first check
Straight answers about products, credits, API access, and failed validations.
What can WA Checker validate?
Choose registration, avatar, or Business account checks. Every product runs synchronously for one phone number.
How are credits charged?
Registration checks cost 1 credit. Avatar and Business checks cost 2 credits. A failed or undetermined upstream result does not keep the charge.
Can I try it without an account?
Yes. The public Checker page offers a protected free registration demo. An account is required for all products, history, and API access.
How do I use the API?
Create an API key in Settings and send one service_type and E.164 phone number to the synchronous check endpoint.
