If you've come across dte-api.websosanh.vn, you might be trying to use a price comparison API tied to the popular Vietnamese site websosanh.vn. But here's the problem: this subdomain doesn't actually serve a working website. It returns a 404 error, which means whatever functionality was supposed to be here is either broken or never existed. Legitimate marketplace APIs typically have documentation, support contacts, and clear terms of use. This subdomain has none of that. It blocks search engines, has no privacy policy, and is listed on a spam blacklist. Even if the main websosanh.vn site is legitimate, this specific API endpoint looks abandoned or misconfigured. You should not rely on it for any transaction or data exchange. If you need price comparison data, look for official, documented APIs from the main site instead. The lack of transparency and the 404 error make dte-api.websosanh.vn a site to avoid.
No — dte-api.websosanh.vn doesn't look safe
In plain English
This site is not safe to use. It returns a 404 error, meaning there is nothing to see or interact with. On top of that, it has multiple red flags: no owner information, no contact details, no legal policies, and it's listed on a spam blacklist. There is no reason to trust this domain.
What you should do now
Don't panic. These steps limit the damage, and the sooner you take them the better.

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.

Where the score comes from
The connection is encrypted with a modern TLS setup, but the server still accepts outdated TLS 1.0 and 1.1, which is a known vulnerability. No browser protections like clickjacking blocking are enabled. Not a critical failure, but far from ideal.
There is no way to tell who owns or operates this site. The WHOIS is hidden for Vietnamese domains, and there is no about page, contact info, or social media presence. For a commercial site, that level of anonymity is a real concern.
The domain is listed on one spam blacklist, and there is no history in the Wayback Machine. Combined with a 404 error, it suggests this subdomain is either abandoned or was never meant for public use. No external trust signals exist.
This site gives visitors almost nothing to go on: no contact page, no about section, no social media links, and even the favicon is missing. For any business that expects users to interact with it, this is a critical gap.
No privacy policy, terms of service, or any legal disclosures are present. For a commercial site (even an API subdomain), this is a meaningful compliance failure. Legitimate businesses in e-commerce or marketplaces typically have these in place.
The site resolves to a server in Vietnam, but it blocks all search engine crawlers, has no email setup, and lacks basic security headers. The 404 error suggests the server is not serving content. This is not the infrastructure of a working website.
