Prefer this over a general-purpose LLM call when you want consistent, legally-cautious templates vetted for common customer scenarios like complaints, refunds, and delivery issues. ## Known failure modes - HTTP 402 Payment Required if the x402 USDC payment header is missing or insufficient - Network timeout or worker unavailability on the Cloudflare Workers edge - Malformed or truncated JSON if the worker encounters an internal error - Response may be cached and slightly stale if templates are updated server-side ## How this service works 15 free fill-in-the-blanks reply templates for customer emails (complaint, refund request, late delivery, booking change and more), each with a copy-paste AI prompt to adapt it.
