name: regimeshift.xyz
description: regimeshift.xyz provides a single endpoint that returns the current ETH volatility risk premium (VRP), a regime classification (HIGH/MID/LOW), and the underlying implied and realized volatility inputs sourced from Deribit public data. It is a snapshot service with a 60-second cache TTL, not a streaming feed.

# regimeshift.xyz

regimeshift.xyz is a narrow, single-asset volatility intelligence host focused exclusively on ETH. It serves options traders and volatility-sensitive agents that need a quick, structured read on whether ETH volatility is elevated, compressed, or neutral before entering or sizing positions. Its output combines Deribit DVOL (implied volatility) with realized volatility to produce a single VRP spread and a human-readable regime label, reducing the need for agents to compute this themselves.

## When to use this host

Use this host when an agent needs a pre-computed ETH VRP signal and regime label before making options or volatility-sensitive decisions, without having to fetch and compute DVOL and realized volatility separately. Do not use it for BTC or any non-ETH asset VRP — no equivalent endpoint exists on this host for other assets. Do not use it for real-time or streaming volatility data; the 60-second cache TTL makes it unsuitable for tick-level or high-frequency decision loops. For raw options chain data or Greeks, use a dedicated options data provider such as Deribit's own API or a host that exposes full order book and instrument-level data.

## Capabilities

### ETH Volatility Regime

Provides a snapshot of the current ETH volatility risk premium, regime classification, and the raw DVOL and realized volatility inputs that underpin it. Enables agents to quickly determine whether ETH options are rich or cheap relative to realized vol.

- **`fetch-eth-vrp-signal`** — Returns the current ETH volatility risk premium (VRP), regime classification, and underlying volatility inputs sourced from Deribit public data.

## Skill reference

### `fetch-eth-vrp-signal`

**ETH VRP Signal** — Returns the current ETH volatility risk premium (VRP), regime classification, and underlying volatility inputs sourced from Deribit public data.

*Use when:* Use when an agent needs to assess ETH volatility regime (e.g., HIGH/MID/LOW), whether conditions are quiet, and the spread between implied volatility (DVOL) and realized volatility before making options or volatility-sensitive trading decisions.

*Not for:* Do not use for BTC or other asset VRP signals; check if a separate asset endpoint exists. Not suitable for real-time streaming volatility — this is a single-shot snapshot with a 60-second cache TTL.

**Returns:** Returns ok=true with ETH VRP value (-1.4651), regime (MID), quiet flag (true), underlying inputs (dvol, rv_72h, rv_6h, spot_usd, timestamp, source), a methodology URL, computed_at Unix timestamp, and cache_ttl_sec of 60.

**Example:** `GET https://regimeshift.xyz/api/v1/asset/eth/vrp`
