# TEIKOS

> TEIKOS is scheduling infrastructure for AI voice agents and AI voice receptionists. Atomic hold-confirm booking, real-time availability, zero double-bookings. Integrates with Vapi, Retell AI, n8n, and any HTTP webhook.

TEIKOS solves the infrastructure gap in the voice AI stack: platforms like Vapi and Retell handle voice/LLM/telephony, but scheduling requires a source of truth. TEIKOS provides database-locked appointment booking via a tool-router API.
