View OpenAPI Document

Jentic publishes the only available OpenAPI document for Vibrato Call API, keeping it validated and agent-ready.

Jentic publishes the only available OpenAPI specification for Vibrato Call API, keeping it validated and agent-ready. The Vibrato Call API powers AI-driven outbound and inbound phone calls. Across 23 endpoints it covers calls, campaigns, contacts, and task templates — the building blocks for automating phone outreach with AI voice. Authentication is HTTP bearer, and the API exposes a clean CRUD pattern across each resource so an integration can list contacts, build a campaign, and launch calls programmatically.

Use Cases

Patterns agents use Vibrato Call API API for, with concrete tasks.

★ Automated Lead Follow-Up Calling

Sales teams configure a campaign that calls every new inbound lead within minutes, using a task template that qualifies the lead and books a meeting if appropriate. Vibrato handles the AI voice, the contact iteration, and the per-call status tracking, so the sales-ops integration only needs to push contacts and read call outcomes.

Create a campaign 'New-Lead-Followup' that calls all contacts created in the last hour using task template id 42.

Single AI Call from a Workflow Trigger

When a workflow tool detects a high-value event (a payment failure, a demo no-show), it can place a single targeted AI call rather than running a full campaign. POST /calls accepts a contact id and task template and returns the call uuid. The integration then polls GET /calls/{id} for status until the call completes.

Place a single call to contact uuid 'cnt_99' using task template 'payment-failure-recovery' and poll GET /calls/{id} until status is final.

Contact List Synchronisation

CRM-driven contact lists feed Vibrato's contacts resource so campaigns target the latest customer record set. POST /contacts adds a contact, GET /contacts lists them with filters, and PATCH /contacts/{id} updates phone or metadata. This keeps the AI calling layer aligned with the CRM source of truth.

List the firm's CRM contacts and POST any missing ones to /contacts in Vibrato.

AI Agent Voice Outreach

An AI agent assigned to a customer-success workflow can place calls, queue campaigns, and update task templates without UI navigation. Through Jentic the agent finds each operation by intent ('place an AI call' or 'create a call campaign') and Vibrato bearer tokens stay in the encrypted vault rather than reaching the agent context.

Create a campaign targeting contacts tagged 'renewal-30d' using template 'renewal-call' and start it.

Why though Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

Vibrato bearer tokens are stored encrypted in the Jentic vault. Agents receive a scoped invocation capability — the raw token never enters the agent's context, which matters because the token authorises real outbound calls that incur cost.

Intent-based discovery

Agents search by intent (e.g. 'place an AI call' or 'create a call campaign') and Jentic returns the matching Vibrato operation with its full input schema for direct execution.

Time to first call

Direct Vibrato integration including auth, contact sync, campaign config, and call-status polling: 2-3 days. Through Jentic: under 1 hour — search, load, execute.

FAQs

Specific to using Vibrato Call API API through Jentic.

Why is there no official OpenAPI spec for Vibrato Call API?

Vibrato does not publish an OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call the Vibrato Call API via structured tooling. It is validated against the live API and kept up to date. Get started at https://app.jentic.com/sign-up.

What authentication does the Vibrato Call API use?

Vibrato uses HTTP bearer authentication — the bearer token is sent in the Authorization header. Through Jentic this token is stored encrypted in the vault and the agent receives only a scoped invocation capability, so the raw token never enters its context.

Can I place a single AI phone call with the Vibrato API?

Yes. POST /calls accepts a contact reference and the task-template id and returns the call's uuid. Poll GET /calls/{id} for the latest status, recording references, and outcome details.

What are the rate limits for the Vibrato Call API?

The spec does not declare explicit rate limits. Vibrato meters concurrent calls and total minutes by plan; production integrations should respect 429 responses with backoff and avoid spinning up many campaigns simultaneously without checking quota first.

How do I create a call campaign through Jentic?

Search Jentic for 'create a vibrato call campaign'. Jentic returns POST /campaigns with its input schema; load it with the contact filter and task-template id, execute, and capture the returned campaign uuid for follow-up calls.

Can I update a contact's phone number via the API?

Yes. PATCH /contacts/{id} accepts the partial update payload — for example a new phone number or metadata — and returns the updated contact record. POST /contacts is used for new records; PATCH is used to keep the list aligned with upstream CRM changes.
