How to interpret the result
Pass means the API appears present; it does not guarantee permission, working hardware or a successful end-to-end operation. Extensions, privacy settings and insecure contexts can restrict functionality despite an available API.
Frequently asked questions
Does Fail mean the whole site cannot work?
No. Different tools need different APIs. A browser can support text tools while lacking a camera or device-specific capability.
