Terms of use

Last updated: 1 September 2026.

1. Service scope

MZ3B Verify provides a beta API for sending and checking one-time verification codes through a WhatsApp session linked by the account owner. The service does not include marketing or bulk campaigns. Real messages are unavailable until the session is connected.

2. Acceptable use

You may use the service to verify a login or phone ownership after obtaining user consent. Unsolicited messages, bypassing sending limits, testing phone numbers without a legitimate basis for processing, and unlawful use are prohibited.

3. Accounts and keys

Customers are responsible for protecting API keys, keeping them server-side and revoking them if a leak is suspected. Keys may be suspended for misuse or security risk.

4. Credits and trial

The one-time trial provides up to 20 messages over 7 days from the first successful number connection. It ends when that period expires even if messages remain, and deleting a number or project does not renew it. Purchased credits are separate and do not expire monthly. One unit is deducted for each message accepted by the sending provider. There is no mandatory operating subscription. A session stops after the trial ends if no credit remains. Administrative grants are not payments.

5. Availability and beta status

The current service is in beta and carries no production availability guarantee. WAHA is not Meta’s official API. WhatsApp may restrict a number or session under its policies or systems. APIs, prices and usage limits may change before general release; customers will be notified of material changes.

6. Suspension

Accounts may be suspended to protect users and the platform or for violations of these terms. Customers may stop using the service at any time. Current packs do not renew automatically.
