Amazon Web Services uses Twilio to provide a service called Ask-a-Human, which allows users with caller-ID enabled phones to call a toll-free number, submit questions and receive answers within an hour. The application is built using ASP.NET and handles all state through Twilio and Amazon Mechanical Turk. This service can be tried out by calling the provided phone number and asking any question, providing instant access to human intelligence for businesses and individuals alike. Additionally, resources such as API documentation, SDKs, tutorials, ebooks, industry reports, webinars, best practices, code samples, and a developer community hub are available for developers building communications and digital engagement experiences with Twilio.
