How it works
The free widget checks the number's format and country against national numbering-plan rules — instantly and privately. The paid Lookup API takes the same number and cross-references it against carrier records, public caller-ID sources, and risk databases, so you get a full report on who's behind it.
Free checks are honest about what the number tells us without a live database call. When you need the caller's name or spam risk, that's where the API tier is worth the price.
