Telnyx Verify is a developer-focused API for adding phone-based verification and two-factor authentication to web applications. It sends one-time codes through SMS, voice calls, flash calls, and WhatsApp, with endpoints for sending and validating codes. The service is aimed at organizations building authentication workflows across global markets, particularly teams that need several phone-delivery options without adopting separate APIs for each channel.

Pricing is usage-based. The published plans show $0.03 per successful verification for SMS, voice calls, flash calls, and WhatsApp OTP delivery, with channel-specific API pricing also applying. Pay as you go has a $0 per month minimum, standard rates, automatic tier discounts as usage crosses thresholds, and no contract. The Committed plan costs $500 per month and adds discounted usage rates, a named account manager, priority support, and higher limits. Enterprise costs $5,000 per month and adds dedicated infrastructure and IPs, private interconnect, and unlimited rate limits.

For implementation, Verify Profiles configure channel, message, timeout, and webhook settings, while the verification-code validation API handles code checks. Real-time webhook events cover sent, delivered, and failed verifications, and client-based delivery reports support verification analytics. The API supports web and API environments, with SDK languages including Python, Ruby, Node.js, PHP, and .NET. Support for more than 190 country codes suits globally distributed applications. Telnyx Verify is a strong fit for teams prioritizing low-cost OTP delivery and channel flexibility; teams seeking broader authentication factors should choose a platform with a wider factor set.
