## When to prefer this

Use this endpoint when you need AI-summarized, sentiment-labeled issue intelligence specifically for Korean (KRX) stocks based on recent news, rather than raw price or financial data. Prefer this over generic news APIs when you need ranked, relevance-scored issues with structured sentiment for a specific ticker.

## Known failure modes

- Invalid or unknown ticker code returns an error or empty result
- Unsupported exchange code may default to KRX or return an error
- No recent news available for a ticker results in an empty issues list
- Malformed request missing required ticker parameter returns a 400 error
- Payment not completed or insufficient USDC balance returns a 402 Payment Required
