ツール（2）
🟢validate_postcode(country, code)
Check whether a postal code has a valid format for a country and return its normalized form (uppercase, official space or hyphen), a format example and the country name. Example: country "NL", code "1234ab" → valid true, normalized "1234 AB". Format check only (Google libaddressinput patterns): it does not confirm the code exists or is deliverable. Countries without postal codes return valid false with reason "no_postal_codes". Read-only. Same engine as GET /v1/validate.
