All URLs referenced in the documentation use the following URL.
https://lookups.twilio.com/v1/PhoneNumbers/{PhoneNumber}TwilioのREST APIはHTTPS経由で提供されます。 データのプライバシーを確保するため、暗号化されていないHTTPはサポートされません。
{PhoneNumber} is the phone number you are requesting information about. Phone numbers can be specified either in national formatting or in standard E.164 format. If providing a number in local national format, please also specify the country as an optional parameter. If no country is provided, this will default to US.
認証
HTTP requests to the REST API are protected with HTTP Basic authentication. To learn more about how Twilio handles authentication, please refer to our security documentation. In short, you will use your Twilio account SID as the username and your auth token as the password for HTTP Basic authentication.
curl -G https://lookups.twilio.com/v1/PhoneNumbers/{PhoneNumber} \
-u '[YOUR ACCOUNT SID]:[YOUR AUTH TOKEN]'You can find your account SID and auth token in your console.
To learn more about authentication and interaction with the Twilio REST API, check out our documentation for requests to the API and Twilio's response.

You can add Lookup-supported add-ons by visiting the Twilio console to enabling the add-on, making sure you have 'Lookups' selected:
When you use AddOns, you can pass additional parameters to the Add-on(s):
