service / x402-phone-carrier-hlr-lookup-8b0cb85d
SiteCheck Agent Intel & Dev
Parses an international phone number (E.164), checks it against Google's open libphonenumber metadata, and returns the country, line type (mobile, fixed line, fixed-or-mobile, VoIP, toll free, premium, pager and more), E.164/international/national formats and the carrier that the number range was originally allocated to. Not a live HLR query: ported numbers keep the original carrier and active/inactive status is not checked.
