Choose this endpoint when you need to automatically generate a draft reply to an email using AI, particularly within an automated workflow or agent pipeline where USDC micro-payments per call are acceptable. It is well-suited for customer support automation, inbox management, or productivity tools that need on-demand email drafting without maintaining a dedicated LLM integration.
