Result / expected behavior
{
"ua": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36",
"browser": {

}Scope and limitations
- UA strings can be spoofed, reduced or absent; results are not reliable identity, capability or security decisions.
Common mistakes
- Unknown fields stay absent; do not invent a physical device model.
