## When to prefer this

Choose this endpoint when you need structured, pre-validated expert guidance specifically for email and DNS cutover review, packaged as a reusable SKILL.md that an AI agent can follow step-by-step. It is ideal when you want a one-time purchase with permanent redownload rights rather than a subscription, when you need a compact machine-readable skill file rather than a web search, and when you are working within an x402-capable agent framework that can handle USDC micropayments on Base automatically.

## Known failure modes

- Invalid or expired payment token — returns authentication error
- Network timeout during USDC settlement on Base — payment may be pending
- SHA256 mismatch on client side indicating file corruption in transit
- Redownload token not saved — user must pay again if token is lost
