## 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 kronos-signals-gex-options-analytics-for-btc-96b4d8ab
```

Example prompt: What's the current gamma flip level for Bitcoin, and is spot trading above or below it? Also show me the max-pain strikes for the upcoming weekly and monthly expiries and the pin-risk score.

## When to prefer this

Use this endpoint when you need structured, pre-computed options Greeks and market-structure signals for Bitcoin specifically — particularly GEX, gamma flip, and max-pain — without having to pull and process raw Deribit order book data yourself. Prefer this over raw exchange APIs when you want an immediately actionable regime label (above/below flip) and pin-risk heuristic in a single call.

## Known failure modes

- Deribit public API unavailable — upstream dependency failure
- Stale data returned if cache has not refreshed within 15-minute window
- Payment failure if x402 USDC payment of $0.04 is not completed
- No options data if BTC options chain is illiquid or expiry is too far out

## How this service works

Gamma Exposure (GEX) and max-pain options tool for BTC and ETH from the Deribit public API. Returns an aggregate GEX strike ladder (dealer-convention net gamma per strike), gamma flip level (zero-cumulative-GEX strike), spot regime above or below flip, max-pain strikes for upcoming weekly and monthly expiries, an expected-move cone (ATM-IV-derived 1-sigma, front expiry), and a heuristic pin-risk score. 15-minute in-memory cache. $0.04 USDC via x402.

## Output

Returns a GEX strike ladder showing dealer-convention net gamma per strike, the gamma flip level (zero-cumulative-GEX strike), whether BTC spot is currently above or below the flip, max-pain strikes for upcoming weekly and monthly Deribit expiries, a 1-sigma expected-move cone derived from ATM implied volatility of the front expiry, and a heuristic pin-risk score. Data is cached for 15 minutes.
