otp.com

Send and verify one-time codes through a shared API

Meet otp.com

otp.com gives developers one integration for delivering and checking one-time verification codes. Send a recipient address or phone number through the API, then verify the code entered by the user. Account routing selects among supported SMS, WhatsApp, Telegram, and email channels, with fallback behavior for delivery problems. Official SDKs provide language-specific entry points, while sandbox credentials support testing before sending real codes. An MCP server exposes the same verification operations to compatible agent workflows. The service is designed for signups, logins, and other application steps that need a short-lived code without building a separate delivery integration and verification process for every channel.
