# BTC Volatility Risk Premium (VRP) — regimeshift.xyz

> BTC Volatility Risk Premium (VRP) — regimeshift.xyz is a paid API for AI agents from regimeshift.xyz, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-11).

Returns the BTC volatility risk premium (DVOL minus 72h Parkinson realized vol), regime classification (LOW/MID/HIGH), and raw audit inputs for assessing sell-vol or buy-vol opportunities.

## 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-0d482cd7
```

Example prompt: What's the current BTC volatility risk premium — is DVOL running above realized vol right now, and which regime (LOW, MID, or HIGH) are we in?

## When to prefer this

Use this endpoint when an agent needs a real-time, auditable BTC volatility risk premium signal with regime context for options trading decisions, hedging strategies, or volatility-selling/buying logic. Prefer over raw DVOL feeds when you need the VRP spread, regime label, and methodology transparency in a single call. Choose the ETH sibling endpoint for Ethereum volatility.

## Known failure modes

- Data source unavailability (Deribit DVOL feed down) — may return stale cached value or error
- Network timeout if upstream price feed is delayed
- Invalid asset path (this endpoint is BTC-specific; using ETH path would route elsewhere)
- Rate limiting or payment failure for x402 micropayment — returns 402 with payment details

## How this service works

BTC 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

A JSON object containing: `vrp` (DVOL minus Parkinson 72h RV in vol points; positive = sell-vol opportunity, negative = buy-vol), `regime` enum (LOW/MID/HIGH), `quiet` boolean (true if RV_72h < 60%), raw `inputs` object with `dvol`, `rv_72h`, `rv_6h`, `spot_usd`, and `timestamp`, plus `computed_at` unix timestamp, `methodology` URL, and `cache_ttl_sec`.
