## 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 bitcoin-volatility-risk-premium-vrp-api-0545e8e6
```

Example prompt: What's Bitcoin's current volatility risk premium and dvol, and what regime is BTC in right now — HIGH, LOW, or something else?

## When to prefer this

Choose this endpoint when you need a pre-computed, ready-to-use Bitcoin volatility risk premium with regime classification — ideal for options traders, quant systems, or risk dashboards that need a single structured payload combining implied vol, realized vol, VRP spread, and regime label without having to compute it themselves. Prefer this over raw price feeds when the derivative metric (VRP) is the primary signal needed.

## Known failure modes

- Payment failure or insufficient USDC balance returns HTTP 402
- Network timeout if the upstream volatility data source is unavailable
- Stale data if the underlying feed has not been refreshed recently
- Malformed response if the volatility computation encounters missing market data

## How this service works

Public data and utility APIs paid per call in USDC on Base (x402). No accounts, no API keys. 174 routes: crypto/equity data, onchain reads, DNS/email/security intel, geo/weather, x402 payment diagnostics, dev utilities and more.

## Output

A JSON object containing: vrp (the volatility risk premium, e.g. 17.1), dvol (implied volatility index, e.g. 55.2), regime (a string classification such as 'HIGH'), and realized_72h (72-hour realized volatility, e.g. 38.1). These metrics together describe the current spread between implied and realized Bitcoin volatility and the prevailing vol environment.
