## 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-eth-gamma-exposure-gex-max-pain-options-tool-a430addf
```

Example prompt: Pull the latest ETH gamma exposure analysis — give me the GEX strike ladder, where the gamma flip level is, whether spot is above or below it, this week's and this month's max-pain strikes, and the pin-risk score.

## When to prefer this

Use this endpoint when you need ETH-specific options market structure intelligence — particularly GEX, gamma flip, or max-pain analysis derived directly from Deribit. Prefer this over generic price feeds when you need dealer positioning context, pin-risk assessment, or volatility cone estimates for ETH options expiries. Not suitable for BTC (use the BTC variant) or for equity/traditional options data.

## Known failure modes

- Deribit public API unavailable or rate-limited — upstream data fetch fails, returns 5xx or error body
- Cache stale beyond 15 minutes if Deribit is intermittently unavailable
- x402 payment not satisfied — returns 402 Payment Required
- No liquid options market data available for requested expiry — incomplete strike ladder
- Invalid or unexpected response format from Deribit — parsing error returned

## 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 structured JSON payload containing: a per-strike GEX ladder (dealer-convention net gamma), the gamma flip strike (zero-cumulative-GEX crossover), a spot regime label (above or below flip), max-pain strikes for the nearest weekly and monthly Deribit expiries, a 1-sigma ATM-IV-derived expected-move cone for the front expiry, and a heuristic pin-risk score. Data is sourced from the Deribit public API and cached for up to 15 minutes. Costs $0.04 USDC per call via x402.
