## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability regimeshift-xyz-17ad6d9b
```

Example prompt: What's the current ETH volatility risk premium — is DVOL running above or below 72-hour realized vol, and what regime are we in right now?

## When to prefer this

Use this endpoint when you need a real-time, auditable ETH volatility risk premium with regime context for options trading decisions. Prefer over generic vol APIs when you need the Parkinson RV methodology, regime classification, and raw input transparency for agent-driven or automated vol strategy execution. The BTC sibling endpoint exists for BTC VRP; use this ETH-specific one for ETH derivatives exposure.

## Known failure modes

- Data source unavailable — DVOL or spot feed unreachable, may return non-ok response
- Stale data — cache_ttl_sec indicates how fresh the response is; high-frequency callers should check computed_at
- Payment failure — x402 micropayment of $0.001 USDC not processed correctly
- Rate limiting — excessive polling may trigger throttling

## How this service works

ETH Volatility Risk Premium — DVOL minus Parkinson realized vol (72h). Positive = sell-vol opportunity, negative = buy-vol. Response includes regime classification (LOW/MID/HIGH), raw inputs for audit (DVOL, RV_72h, RV_6h, spot), timestamp, and open methodology URL.

## Output

Returns a JSON object with: ok (bool), asset ('ETH'), vrp (DVOL minus Parkinson RV_72h in vol points; positive = sell-vol opportunity), regime enum ('LOW'/'MID'/'HIGH'), quiet flag (true if RV_72h < 60%), raw inputs object (dvol, rv_72h, rv_6h, spot_usd, timestamp), computed_at unix timestamp, cache_ttl_sec, and a methodology URI for audit.
