If you've come across commerceapi.office.net and wondered whether it's safe, here's the short answer: this looks like a legitimate API service run by Microsoft, not a scam. The domain sits on office.net, a well-known Microsoft property, and the SSL certificate is issued by Microsoft itself — that's a strong identity signal. The site itself returns a permission-denied message, which is exactly what you'd expect for an internal API endpoint. It's not meant for public browsing.
What should you watch for? The certificate expires in less than a month. If you're integrating this API into a product, you'll want to make sure Microsoft renews it on time — otherwise connections could briefly fail. Beyond that, the security setup is standard for an API: no fancy security headers, but the underlying encryption is modern and the hosting is on Microsoft's own network.
There are no commerceapi.office.net reviews out there because it's not a consumer-facing website. No Trustpilot, no web archive history — that's all normal for a backend service. If you're a developer looking to use this API, the evidence says it's safe to proceed, just keep an eye on the certificate renewal date.
