Check WhatsApp registration, avatar availability, and Business account status before you message or route a contact. Use the dashboard or the API, with balance refunded when a result cannot be determined.
WhatsApp Registration CheckNo sign-in required. Daily demo limits apply.
Definition
Before you check
The dashboard and API send one submitted phone number to the backend and return the selected status fields in the same request.
Enter the phone number your workflow wants to check.
ws returns registration; ws_avatar adds avatar availability; ws_business adds the Business account field.
Read the returned JSON immediately in your workflow. Run a new check whenever you need an updated status.
Verification products
All three products use one synchronous endpoint. Select a service type to control the returned fields and balance cost.
wsConfirm whether a phone number is registered on WhatsApp.
ws_avatarCheck registration, whether the WhatsApp account has set an avatar, and return the avatar URL when available.
ws_businessCheck registration and identify whether the number uses a WhatsApp Business account.
Use cases
Check registration and available account details before outreach, record updates, or automated routing.
Remove numbers that are not registered before campaign upload or sales assignment.
Attach registration, avatar, or Business account results to existing contact records.

Features
Run checks from the dashboard or API, manage balance and API keys, and review every result in one place.
Every check returns in the same HTTP response. There is no polling step or webhook setup.
Registration check (ws), avatar check with profile URL (ws_avatar), or Business account check (ws_business) — all on the same API endpoint.
Balance, API keys, history, and product-level reporting sit in one dashboard instead of separate tools.
Workflow
Start with a manual check or connect the same validation service to your application.
Sign up to access the dashboard and manage your profile and API keys from one place.
Balance is deducted up front for each check. If the check fails or the result is undetermined, Balance is automatically refunded — you only pay for a usable result.

FAQ
Answers on WhatsApp products, balance, API access, and failed validations.
WA Lookup offers three products: ws (registration check), ws_avatar (registration + avatar URL), and ws_business (registration + Business account type). Every check is synchronous and returns in the same HTTP response. It does not check online status, last seen, or message history.
Balance is charged only for completed checks. It is purchased once with no subscription and is refunded if the check fails or the result is undetermined.

Create an API key in Settings, then POST to /api/v1/check with the X-API-Key header, the phone number you want to check, and a service_type of ws, ws_avatar, or ws_business. The endpoint returns a synchronous JSON response.
No. A result reports the WhatsApp status fields available at the time of the check. You remain responsible for consent, recipient preferences, and applicable platform rules before contacting anyone.
