Mock the Retell AI voice agent API: simulate call registration, agent and LLM management, and phone-number provisioning without a real Retell account.

[01]

About

overview

Mock the Retell AI REST API for voice agents and AI phone calls. Covers call registration and lookup, agent CRUD, Retell LLM configuration, phone-number provisioning and outbound call creation. Mock responses match the live Retell shape so client SDKs, dashboards, and voice integrations can be tested without a Retell API key or live calls.
