Radiov2.cekainternational.com doesn't behave like a typical website. When you visit, you get a JSON error message instead of a homepage. That alone is unusual for any consumer-facing service. For an API endpoint it could be normal, but it raises questions about whether this subdomain is actually meant for public use.
Most legitimate services with a public API provide some documentation, a status page, or at least a working endpoint. Here, there's none of that — no contact info, no privacy policy, no record in the Wayback Machine. The site does have a valid SSL certificate and is protected by Cloudflare, so basic security is in place. It also isn't on any blacklists or flagged by Google.
Still, the lack of any web presence or history makes it hard to verify who operates radiov2.cekainternational.com or what it's supposed to do. If you're considering using this API, you'll need more evidence that it's maintained by a known organization. Without that, treat it as an unknown and proceed carefully.
