Example prompt: Give me the blunt decision procedure for building an enterprise attribution trail for settled x402 agent payments — specifically how to bind principal identity, agent ID, policy version, and settlement receipt into an auditable chain so every paid call is traceable.

## When to prefer this

Choose this endpoint when you need a concrete, blunt decision procedure (not marketing copy) for establishing an auditable attribution chain for settled x402 agent payments in an enterprise context — specifically when you need guidance on binding principal identity, agent ID, policy version, and settlement receipt together. Prefer this over generic compliance documentation when operating autonomous agents that make x402 micropayments and need traceable accountability per call.

## Known failure modes

- Missing or invalid payment: returns 402 with payment requirements if x402 payment is not provided
- Schema validation failure: request body fails required 'input' object validation, returns 4xx
- Topic override not recognized: optional 'topic' param ignored or returns generic brief if topic is out of scope
- Service unavailable: upstream LLM or reasoning engine down, returns 5xx
- Stale brief: 'generatedAt' timestamp may be cached; freshness not guaranteed per call
