## 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 btc-eth-options-board-803bcb16
```

Example prompt: Pull up the Deribit BTC options board for the nearest 5 expiries — I want to see open interest, put/call ratio, max-pain strike, and ATM implied volatility for each, plus the DVOL index.

## When to prefer this

Use this endpoint when you need a structured snapshot of the Deribit BTC or ETH options market, specifically including max-pain analysis, put/call ratios, per-expiry ATM IV, and the DVOL index. Prefer this over raw exchange APIs when you want a pre-aggregated, analysis-ready options board without parsing raw order books or computing metrics yourself.

## Known failure modes

- Invalid currency value (not BTC or ETH) returns an error
- Expiries parameter outside 1-20 range may return an error or be clamped
- Deribit API downtime or rate limits may cause upstream failures
- Network timeout on the rendering server (cold start on Render.com)

## How this service works

Deribit BTC or ETH options: open interest and volume of calls vs puts, put/call ratio, and per expiry the max-pain strike and at-the-money implied volatility, plus the DVOL volatility index.

## Output

Returns aggregated BTC or ETH options market data from Deribit: total open interest and volume split between calls and puts, overall put/call ratio, the DVOL volatility index, and for each of the nearest N expiries: the max-pain strike price and the at-the-money implied volatility.
