Example prompt: Give me a blunt decision procedure for when I should pay for notification inbox delivery — what must a paid comms receipt be bound to (deliverable hash, thread ID, delivery proof), and how should I refuse inboxes with weak merchant contracts?

## When to prefer this

Choose this endpoint when an agent or agent-builder needs a concrete, non-marketing decision procedure specifically for payment hygiene around notification inboxes — covering receipt binding requirements and merchant contract evaluation. Prefer over general compliance guides when the context is x402 micropayment flows and autonomous agent comms.

## Known failure modes

- Payment not provided — endpoint requires $0.002 USDC via x402 before returning the paid brief
- LLM generation failure — result may indicate generationSource as deterministic fallback
- Invalid query params — unsupported values for meta or topic may be silently ignored or cause 400
- Network or provider downtime on k2so.wrong.systems — returns no result
