## 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 deribit-options-market-summary-btc-eth-sol-174554ba
```

Example prompt: What does the Deribit options market look like for BTC right now — give me the ATM implied volatility, max pain strike, and put/call ratios for the nearest expiries.

## When to prefer this

Choose this endpoint when you need a quick, aggregated snapshot of Deribit options market structure for BTC, ETH, or SOL — specifically ATM implied volatility, max-pain strike, and put/call ratios across near-dated expiries. Prefer this over raw Deribit API calls when you want pre-computed metrics without handling raw per-instrument data. Not suitable if you need 25-delta skew, per-option greeks, or order flow data.

## Known failure modes

- Unsupported currency value (not BTC, ETH, or SOL) returns an error
- Deribit public API unavailable or rate-limited causes upstream fetch failure
- Stale or incomplete data if Deribit's book summary is delayed
- No 25-delta skew data (requires per-option greeks, not available in this endpoint)
- No order flow data available

## How this service works

Deribit option market summary for BTC, ETH or SOL: put/call open-interest and volume ratios, max-pain strike and ATM mark implied volatility for the nearest expiries. Computed from Deribit's public book summary. No 25-delta skew (needs per-option greeks, not fetched) and no order flow.

## Output

Returns a JSON object with: spot price, currency, timestamp, total open interest for puts and calls, put/call volume ratio, put/call open interest ratio, and a term structure array for each near expiry containing the expiry label, number of instruments, ATM mark implied volatility (%), and max-pain strike. Data is sourced from Deribit's public book summary endpoint and computed server-side.
