Building or testing flows that need SMS OTP? SMS Duo offers pay-per-use virtual numbers for verification receive. Use the shop to buy sessions; where the site exposes console or API keys, integrate from your own account — we do not publish invented endpoint URLs on this page.
Developer intent landing. Check the live shop / account console for current integration options. Delivery not guaranteed.
Open Shop →Honest developer framing: shop first, then any console/API your account actually provides.
Teams often search for "API SMS verification" when they want to automate receiving one-time codes. SMS Duo's primary path is the web shop: select a service and country, purchase a session number, and read the OTP in the dashboard. If your account shows API or key settings, use those official controls — this landing does not invent base URLs, sample cURL, or undocumented methods.
Automation still depends on stock and app acceptance. Virtual ranges can be blocked. We do not claim free API tiers or 100% delivery. Retry with another country when a number fails.
SMS Duo is an independent SMS receive service. Follow each app's terms and use verification only for legitimate access and testing you are authorized to run.
