Check Verification Code

Check a verification code submitted by a user against an active Vonage Verify v2 request. Also supports cancelling an in-progress verification. Supports API key/secret or application JWT. Checking consumes attempts; cancellation has provider timing restrictions.

Verify User

Start a user verification (2FA) request using the Vonage Verify v2 API. Sends a one-time code to the user via one or more channels (SMS, WhatsApp, voice, email, or silent authentication) with automatic failover. Supports API key/secret for basic synchronous use and application JWT for application callbacks and advanced features.

Send Sms

Send an SMS using the Vonage SMS API (legacy). This is a simpler alternative to the Messages API for sending plain text SMS. Uses API Key/Secret authentication and does not require a Vonage Application.

Make Call

Initiate an outbound voice call using the Vonage Voice API. Control call flow with NCCO (Nexmo Call Control Objects) actions or a remote answer URL. This tool calls one phone number. Acceptance can incur charges and trigger external callbacks. Requires the **API Key, Secret & Application JWT** auth method.

Number Insight

Look up intelligence about a phone number using the Vonage Number Insight API. Returns information about number validity, format, carrier, type, reachability, and roaming status. Three tiers are available: - **Basic**: Country, international/national format - **Standard**: Adds carrier name, type (mobile/landline/VoIP), ported status - **Advanced**: Adds reachability, roaming status and validity flags. Statuses 43–45 are partial results.

Send Message

Send a message across multiple channels including SMS, MMS, WhatsApp, Facebook Messenger, Viber, and RCS using the Vonage Messages API. Supports text, image, audio, video, file, and template message types depending on the channel. Supports API key/secret or application JWT authentication; application authentication enables application webhook settings.

List Calls

Retrieve voice call records from the Vonage Voice API. Filter by status, date range, or conversation. Use this to monitor call activity, check call statuses, or look up a specific call by UUID. Requires the **API Key, Secret & Application JWT** auth method.

Manage Applications

Create, list, update, or delete Vonage Applications. Applications are containers for capabilities (Voice, Messages, RTC, VBC) with their own webhook URLs and key pairs. Uses API key and secret authentication. Creation requires a caller-owned public key; private keys are never returned. Updates preserve omitted native settings without a concurrency guarantee. Deletion is permanent.

Manage Call

Control an active voice call: hang up, mute/unmute, earmuff/unearmuff, or transfer to a new NCCO flow. Can also play text-to-speech, stream audio, or send DTMF tones into a call. Requires the **API Key, Secret & Application JWT** auth method.

Get Account Info

Retrieve Vonage account information including current balance, auto-reload status, and subaccount details. Can also create subaccounts using a secret you already hold and transfer credit or balance between accounts. Subaccounts require restricted API access; financial writes can incur retained effects.

Manage Numbers

Search for available virtual phone numbers, list your owned numbers, buy new numbers, cancel (release) numbers, and update number configuration. Combines number search, purchase, and management in one tool.
