With the Bandwidth Ruby SDK by Bandwidth, users are provided with tools to access such API methods as managing user's applications, searching free local or toll-free phone numbers, controlling endpoints of domains, sending and listing SMS/ MMS messages, and more. The Bandwidth API allows users to make calls to get information about an account, get a list of transactions made on an account, as well as calls for phone numbers, messages, calls, media, applications, errors, and other resources.
YouMail launched its Spam Risk API. YouMail uses algorithms to analyze a database of hundreds of millions of phone numbers to determine the likelihood a particular phone number is spam. Historical call patterns and crowdsourced data are combined to determine an OK, caution, or danger designation.
