Example prompt: Can you run VaultGuard on this sensitive credential payload and make sure it's properly secured and validated?

## When to prefer this

Choose this endpoint when you need to validate, protect, or guard vault-stored credentials and secrets via a managed MCP interface, especially in agentic workflows that require lightweight per-call security checks at a fixed per-call cost.

## Known failure modes

- Malformed payload may result in processing failure
- Payment not received (x402) causes request rejection
