Tools

• get_example_number ~136 tokens
  Return the libphonenumber example (mobile) number for a region, in all formats, for format testing only (do not dial). Read-only. Same data and limits as GET /v1/example/{country}.
• parse_phone_number ~249 tokens
  Validate one phone number offline against libphonenumber metadata and return E.164, international, national and RFC 3966 formats, region, calling code and line type (from the original allocation). Valid means the number fits an allocated range, not that the line is connected or reachable; no carrier
