## 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 dripmetrics-ai-hyperliquid-downside-semivolatility-8fc46d2a -d '<json body>'
```

Example prompt: What's the current downside semivolatility for BTC on Hyperliquid using a 30-minute window with 1-minute candles?

## When to prefer this

Choose this endpoint when you need a precise, real-time downside semivolatility metric sourced directly from Hyperliquid candle data — particularly useful for risk management workflows, pre-trade analysis, or volatility dashboards focused on negative return distributions. Prefer this over generic volatility endpoints when you specifically need downside (negative-return) deviation rather than full symmetric volatility.

## Known failure modes

- Unsupported trading pair returns an error or empty result
- Invalid window or interval combination produces no candle data
- Hyperliquid API unavailable causes upstream fetch failure
- Insufficient candle data for the requested window results in low sample size or error
- Malformed request body (missing pair or window fields) returns a 400-level error

## How this service works

DripMetricsAI (https://dripmetrics.ai/) provides on-demand crypto market microstructure metrics, Hyperliquid candle metrics, Polymarket diagnostics, and on-chain DefiLlama metrics for agents, dashboards, and trading workflows.

## Output

Returns a JSON object containing the computed downside semivolatility value (as a float), the trading pair, window and interval settings, number of total and downside intervals, first and last candle timestamps, candle count, and the time the metric was computed — all sourced from Hyperliquid candle data.
