An official, unmodified Nintendo Switch cannot run NSP files from the internet. To play these files, a user must modify their console with Custom Firmware (CFW), such as Atmosphère. This process usually requires a console that is vulnerable to a hardware exploit (often referred to as an "unpatched" V1 Switch). Newer Switch models (V2, Switch Lite, and Switch OLED) are harder to mod without expensive hardware modifications (installing a modchip).
