If you have come across api.amemv.com.c.dsa.cdnbuild.net, it is likely not a website you would browse in a browser. The domain appears to be a backend API endpoint, possibly part of a content delivery network for ByteDance services like TikTok or Douyin. The most telling signal is the SSL certificate: it is issued for a different domain (snssdk.com) and does not match the address you are visiting. Legitimate infrastructure endpoints always have valid certificates that match their hostname. Without that, any data exchanged is vulnerable to eavesdropping or tampering. The domain also has no web archive history and very little public information, which is unusual for an active service. While it is not flagged by Google Safe Browsing or blacklists, the certificate issue alone is a dealbreaker. If you see this domain in an app, network log, or configuration file, treat it as a serious red flag. Do not rely on it for any secure communication.
No — api.amemv.com.c.dsa.cdnbuild.net doesn't look safe
In plain English
This domain is not a typical website you would visit. It is a backend API endpoint, and its SSL certificate is invalid, a critical security failure. Without a valid certificate, any data sent to or from this service is not properly encrypted, making it untrustworthy. I would avoid any interaction with this domain.
What you should do now
Don't panic. These steps limit the damage, and the sooner you take them the better.
Don't enter any details
No passwords, card numbers or personal information — even if the site looks professional.
Close the tab
Especially if you got here from an email, text message or social media ad.
Already paid? Call your bank
Contact your bank or card provider right away. They can often stop or reverse a recent payment.
Warn others
Report the site and share this check with anyone who sent you the link.
Where the score comes from
The SSL certificate is invalid for this domain, which means any connection is vulnerable to interception. This is a critical flaw for any service, especially an API endpoint.
The domain ownership is obscured, and the certificate is issued for a different ByteDance domain, suggesting a configuration error or a potential impersonation attempt.
No blacklist flags or Google Safe Browsing issues, but the domain has no web archive history, which is unusual for a service that should be in use.
As a backend API, it's normal to lack an about page or contact info, but the lack of any public-facing identity is still a concern.
No legal pages are expected for a non-consumer service, so this is not a red flag.
The domain resolves to multiple IPs across different providers, but the lack of basic security headers and DNSSEC is typical for many CDN endpoints.
