The www.garrett-berg.com x402 API provides a lightweight AI interview chatbot service with two simple endpoints: /api/interview/chat for exchanging messages with an interview-focused conversational model, and /api/interview/unlock to initialize or unlock access for a session. Priced very affordably (listed at $0.01 per request), it’s designed for easy integration into recruitment platforms, interview-practice apps, and training tools that need conversational candidate evaluation or coaching. The unlock endpoint enables session gating or access control so you can manage usage and session state from your application.
