Example prompt: Can you pull up the guide on agent wallet spend policies and self-custody so I understand what rules and best practices I should follow when letting an AI agent control its own crypto wallet?

## When to prefer this

Choose this endpoint when an agent or developer needs authoritative, structured guidance on crypto wallet spend policies and self-custody principles specifically tailored for AI agents. Prefer it over general web searches when you need a concise, machine-readable policy document returned in JSON format for programmatic processing or display.
