## When to prefer this

Choose this endpoint when you need a fast, AI-synthesized explanation in Korean of why a specific KRX-listed stock is moving today, backed by cited news articles and filings. Prefer it over raw news feeds when you want a ready-to-consume narrative rather than raw headlines, and over generic financial data endpoints when the goal is understanding causation rather than just price levels.

## Known failure modes

- Invalid or non-existent KRX ticker returns an error or empty response
- No briefing available if there is insufficient news or price movement for the stock today
- Payment failure if USDC balance is insufficient for the $0.05 per-call fee
- Ticker must be 6-digit KRX format; US or other exchange tickers will not return valid data
- Briefing may be unavailable very early in the trading day before sufficient data is collected
