Phone intelligence for an E.164 number, in two products the caller picks between: "name" returns the US CNAM caller name plus the carrier data, and the cheaper "carrier" returns the carrier, line type, mobile network and rate-center location alone. You are charged only on a result: no name found, or an invalid number, costs nothing. Agent guide: https://tenjin.blog/llms.txt
