Example prompt: Pull the current volatility regime classification for the equities/options market from ShadowQuant — I want to know whether we're in a high-vol or low-vol environment right now, including how fresh the data is and what methodology was used.

## When to prefer this

Choose this endpoint when you need a machine-validated, provenance-tagged volatility regime classification for equities/options markets and can pay $0.01 USDC per call via x402 on Base. It is preferable over generic data feeds when you need embedded methodology transparency, freshness indicators, and a track record alongside the regime signal — not raw implied volatility numbers.

## Known failure modes

- 402 Payment Required if x402 USDC payment on Base is not included or insufficient
- Stale data flag (freshness.stale = true) if the regime data has aged beyond acceptable threshold
- Missing or invalid ticker/symbol parameter may return a 4xx error
- Service unavailability on Cloudflare Workers edge may return 5xx
- Data may lag intraday regime shifts depending on methodology refresh cadence

## Output

A JSON envelope containing: a 'data' field with the volatility regime study payload (e.g., high/low/transitional regime classification), a 'provenance' object (producer identity, methodology description, generated_at timestamp, freshness metrics including age_hours and a stale boolean, and track record), a disclaimer, and terms of use. The response is research data, not investment advice.
