Example prompt: What's the current KRW macro stress score and which components — VIX, US treasuries, foreign ownership, or semiconductor equities — are driving it most right now?

## When to prefer this

Choose this endpoint when you need a single, normalized macro stress signal for KRW with regime context rather than raw price data — especially useful for risk gating in trading bots, macro dashboards, or any workflow that needs a quick-to-interpret 0-100 stress score with factor attribution. Prefer this over raw FX rate endpoints when you need directional regime classification, not just spot pricing.

## Known failure modes

- Payment not provided or invalid x402 header — returns 402 Payment Required
- Upstream market data unavailable — may return stale or error response
- Rate limiting if called too frequently without proper payment
- Network timeout if called during market data refresh window

## How this service works

KRW Macro Stress Score (0-100) — combined signal from US 3Y treasury, VIX, foreign ownership proxy (SK Hynix + Samsung, mcap-weighted), USD/KRW momentum, and Korean semiconductor equity. Rolling 120d percentile over 2yr backfill. Regime + direction + per-component breakdown. Positioning: KRW macro stress, not kimchi-premium prediction.

## Output

A JSON object containing a composite KRW macro stress score from 0 to 100 (rolling 120-day percentile over a 2-year backfill), a regime label (e.g. stressed/neutral/calm), a directional signal, and a per-component breakdown covering US 3Y treasury, VIX, foreign ownership proxy (SK Hynix + Samsung mcap-weighted), USD/KRW momentum, and Korean semiconductor equity.
