## 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 agentfeed-realized-volatility-for-usdt-perps-84b28244
```

Example prompt: What's the realized volatility on SOLUSDT right now — give me the 7-day and 30-day annualized numbers plus how much it's ranged today, so I can size my position.

## When to prefer this

Choose this endpoint when you need realized volatility metrics (7d and 30d annualized) and intraday range data for any USDT-margined perpetual futures symbol on Bybit. It is purpose-built for position sizing and risk management in crypto derivatives workflows. Prefer it over generic price feeds when you specifically need historical volatility statistics rather than just a current price.

## Known failure modes

- Missing or invalid 'symbol' query parameter returns an error
- Symbol not found on Bybit (e.g. non-USDT pair or delisted perp) may return empty or error
- Payment not completed (x402 flow) results in 402 response with no data
- Insufficient daily kline history for a newly listed symbol may affect vol calculation accuracy

## How this service works

Realized volatility for any USDT perp: 7-day and 30-day annualized from daily closes, plus today's range in %. Use when you need to answer: How volatile has this perp been? A position-sizing input.

## Output

A JSON object containing the symbol, data source (bybit_daily_klines), today's high-low price range as a percentage, 7-day annualized realized volatility as a percentage, and 30-day annualized realized volatility as a percentage.
