REST API gives engineering teams on-demand virtual numbers across more than 500 platforms, cutting the manual work of testing one-time-password flows

SMSFAST, an online service that provides temporary virtual phone numbers for receiving SMS verification codes, has expanded developer access to its REST API, giving engineering teams a way to pull virtual numbers on demand and automate the testing of SMS and one-time-password flows across more than 500 platforms.

Verification testing is one of the slower jobs in software development. Teams building sign-up, login and two-factor features often check them by hand, buying or borrowing numbers and typing in codes one at a time. SMSFAST said its API removes that step by letting a script request a number, receive the incoming message and confirm the flow worked, with no person in the loop.

The API ships with documentation for Python, Node.js, PHP and Go, and works with any environment that can send an HTTP request. Numbers are available in more than 190 countries, which lets teams test how a verification flow behaves for users in different regions rather than assuming one market stands in for the rest.

“Every product team that ships a login screen has to test verification, and most still do it the slow way,” said Spokesperson Name at SMSFAST. “The API turns a manual chore into a few lines of code, so engineers can run those checks automatically and get back to building.”

Pricing for API use follows the same pay-on-delivery model as the rest of the service. Numbers start at $0.21, the charge returns to the account balance automatically when no code arrives, and higher volume moves teams into loyalty tiers that lower the per-number cost by up to 32%.

The company said developer demand has become one of the faster-growing parts of its business, alongside individual users who rely on virtual numbers to keep personal phone numbers off sign-up forms.
