That’s exactly the kind of nightmare scenario that inspired us to create Prelude (https://prelude.so/). Authentication flows are targeted by fraud like SMS pumping that leaves companies with super high bills that make no business sense.
Our API helps apps take control of their SMS verification costs by proactively blocking fraudulent and suspicious verification attempts before they ever trigger an SMS. On top of that, we let users set daily limits as an additional safety net, so surprises like this don’t happen.
