VAPI vs SCiNESTA: The Real Cost of Building on an AI Agent API

VAPI, Bland AI and Retell AI sell the same thing: a raw voice API. You wire up your own telephony, write your own prompts, build your own interruption handling, and pay per minute whether the call goes well or not. Teams spend $299 a month or more before the first useful call happens.

What you are actually buying with an API

An API gives you speech-to-text, an LLM turn, and text-to-speech. It does not answer your phone. It does not know your business. Every feature a caller hears, your team builds and maintains, and usage pricing means a viral campaign or a chatty caller quietly grows the bill.

What SCiNESTA includes instead

SCiNESTA ships a finished AI phone agent, not a parts kit. It answers calls, books appointments, qualifies leads, routes conversations, and logs everything to the built-in CRM. You describe your business in plain language; the agent handles the rest.

  • Unlimited agents and numbers on your plan, no per-minute meter running on core usage
  • Natural interruption handling and memory across the conversation
  • Booking, tagging, notes and pipeline updates happen during the call, not after
  • Call recordings, transcripts and analytics built in

When an API still makes sense

If you have engineering time and want to hand-roll every millisecond of the conversation, an API is a fair choice. For everyone else, the finished agent wins on both cost and time. See how the SCiNESTA agent works or start for $93 a year.
