## 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 agent402-options-ticker-292c48b9 -d '<json body>'
```

Example prompt: Pull the live Deribit options ticker for the nearest-expiry at-the-money BTC call, including the Greeks, implied volatility, and 24h stats.

## When to prefer this

Use this endpoint when you need real-time, granular options data from Deribit — specifically Greeks, implied volatility surfaces, and live bid/ask — rather than simple spot prices. Prefer this over generic crypto price feeds when options analytics (delta hedging, IV monitoring, vega exposure) are required. Best for agents operating in crypto derivatives, options market-making, or risk management contexts.

## Known failure modes

- Invalid or expired instrument name returns an error — use a valid Deribit instrument like BTC-PERPETUAL or ETH-27MAR26-3000-P
- Unsupported currency (not BTC or ETH) may fail or return unexpected results
- If the option has expired or is not tradeable, the state field may reflect 'closed' or the endpoint may return an error
- Network or Deribit API downtime may cause fetch failures
- Ambiguous combination of currency and type may not resolve to a unique instrument

## How this service works

One options instrument live: mark, last, bid and ask with sizes, index price, open interest, mark, bid and ask implied volatility and the full greeks (delta, gamma, vega, theta, rho). Use it when an agent holds or is quoting a specific contract and needs its current risk numbers.

## Output

Returns a JSON object with the Deribit source, resolved instrument name, fetchedAt timestamp, and a full ticker object containing: ask/bid/mark implied volatility, best bid/ask prices, last price, mark price, 24h low/high/volume/volume-USD/price-change-pct, Greeks (delta, gamma, theta, vega, rho), open interest, underlying index and price, and index price.
