Vapi is a voice AI platform for building, testing, and deploying voice agents at scale, positioned as the infrastructure layer for phone and web voice interactions rather than a single agent product - it orchestrates speech-to-text, LLMs, and text-to-speech providers behind one API.
| Plan | Price | Included | Notable |
|---|---|---|---|
| Build | $0.05/min (Vapi platform fee) | 60+ minutes included; 10 call concurrency (additional lines $10/mo each) | Custom voices and model access, Email + Discord community support, SMS/chat at $0.005/msg |
| Scale | Custom (annual contract, committed volume) | — | Volume-based per-minute pricing, SOC 2, HIPAA, PCI, SSO, RBAC, Data residency options |

Vapi is an API-first voice AI platform: developers configure assistants (model, voice, transcriber) and either place/receive calls through Vapi's telephony or embed voice into web and mobile apps via SDK. It publishes a documented REST API with an OpenAPI 3.0 specification, plus a hosted MCP server for connecting AI coding/chat clients directly to a workspace's assistants and call data.
Development teams building voice-agent products or embedding voice into an existing product (support, lead qualification, scheduling) who want an API/SDK layer over multiple STT/LLM/TTS providers rather than building that orchestration themselves. The vendor's own marketing leans toward enterprise-scale phone-support and outbound use cases.
Usage is metered per minute ($0.05/min Vapi platform fee alone, before model/voice provider costs), plus a $10/month charge per concurrent call line above the 10 included - so high-concurrency, high-volume deployments accumulate real infrastructure cost on top of per-minute AI provider billing. Compliance add-ons are priced separately and steeply (HIPAA $2,000/mo, Zero Data Retention $1,000/mo on top of the base plan), which prices out small teams that need those guarantees. Teams wanting a single fixed-price seat license rather than usage-based billing, or wanting a fully managed voice-agent product rather than an API they configure themselves, are not the target.

Yes.
The Build plan is usage-based: $0.05/min platform fee, 60+ minutes included, 10 call concurrency ($10/mo per extra line), plus pass-through model/voice provider costs. The Scale plan is a custom annual contract with committed volume and enterprise security features (SOC 2, HIPAA, PCI, SSO).
No - HIPAA compliance is a $2,000/month add-on and Zero Data Retention is a $1,000/month add-on on top of the base plan, on both Build and Scale.
Yes - the pricing page states model provider costs are passed through at cost, and are free if you bring your own API key for that provider.
Both. Vapi supports inbound/outbound telephony (no-code assistant creation from the dashboard) and web/mobile voice integration via SDKs.
