README

Country Calling Code is a phone number country code API that looks up international dialing codes and official names from a two-letter ISO country code. It returns an array of calling prefixes, standard country identifiers and, on request, the country's exit and trunk prefixes, other regions sharing its code, valid number lengths and example numbers by line type.

The Country Calling Code API provides a simple, reliable way to integrate country calling code functionality into your applications. Built for developers who need production-ready country calling code capabilities without the complexity of building from scratch.

                'x-api-key': 'YOUR_API_KEY_HERE'
            }
        });

        const data = await response.json();
        console.log(data);
    } catch (error) {
        console.error('Error:', error);
    }
}

callCountryCallingCodeAPI();
