# Vapi

Developer platform for building voice AI agents with your choice of speech, language and voice models.

Vapi is an API-first platform for building voice AI agents that handle phone and web calls. Developers pick the transcriber, language model and voice provider, then connect tools, phone numbers and workflows. Vapi charges a per-minute hosting fee and passes model costs through at cost, which makes it a common base for agencies and product teams building custom phone agents.

Price: $5 free credits; $0.05/min hosting plus model costs. Site: https://vapi.ai/.
