Key gotchas
- `type` field is NOT always present — Turkey, Japan, Germany, India, Brazil omit it (probably libphonenumber metadata gaps). US, UK, Australia include it. Types seen: FIXEDLINE, MOBILE, FIXEDLINEORMOBILE, TOLL_FREE.
- `default_country` is ISO 3166-1 alpha-2 (e.g., "US", "BR", "TR") — required for numbers without international prefix.
- Country-specific national formatting — US uses parentheses
(212) 555-0100, Japan uses dashes03-1234-5678, Turkey uses paired digits0532 123 45 67. - `format` on invalid input returns error TEXT (not JSON object) —
"phone tool failed: cannot parse: invalid". Parse gracefully returns{valid: false}. - Based on Google's libphonenumber — covers 200+ country/region codes with accurate validation rules.
