When you type in a website address and get a 404 error instead of a real page, that's a clear warning. Rtcapi.my1003app.com is not a functioning website — it's a blank endpoint returning an error message. Legitimate API services, which this subdomain pretends to be, always have documentation, a developer portal, and support contact. This site has none of those. There's no company name, no privacy policy, and the domain owner's identity is hidden from the WHOIS database. If you're looking for an API to integrate into your project, this is not a place to start. The question 'is rtcapi.my1003app.com a scam' is less about fraud and more about the fact that there's no service here at all. Stay away until you see real evidence of a working product and a company behind it.
No — rtcapi.my1003app.com doesn't look safe
In plain English
This site isn't just suspicious — it's a dead end. The homepage returns a 404 error, there's no contact information, and the owner is completely hidden. There's no reason to trust it because there's nothing to use.
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.
Already paid? Call your bank
Contact your bank or card provider right away. They can often stop or reverse a recent payment.

Where the score comes from
The site has a valid SSL certificate and passes Google's safety checks. But because the server returns a 404 error and doesn't actually load, the security setup is meaningless for users.
Whoever owns this domain is completely invisible. The WHOIS database shows no record at all, which is unusual even for a brand new site and makes it impossible to hold anyone accountable.
The domain isn't listed on any blacklists, but that's only because it's too new to have been noticed. There's no history in the Wayback Machine, so we have no track record to judge.
There is nothing here: no about page, no contact info, no social media links. You cannot figure out who runs this site or how to reach them.
No privacy policy, no terms of service. Even a basic personal blog typically has a privacy notice these days. The total absence is a red flag.
The domain resolves to an IP and the connection is encrypted, but that's where the good news ends. There's no email setup, no security headers, and no robots.txt. The 404 error confirms the site isn't actually running.
