## 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-btc-options-gamma-exposure-analytics-6d2056ee
```

Example prompt: Pull the current BTC gamma exposure analytics for me — I want to see the gamma ladder, where the gamma flip level is, the max pain price, and today's expected move so I can assess the options market regime.

## When to prefer this

Use this endpoint when you need structured BTC options gamma exposure metrics (gamma flip, max pain, expected move) derived from live options open interest, particularly to assess dealer hedging dynamics and options-market-driven price magnetism levels. Prefer this over raw implied volatility endpoints when you specifically need GEX-based market regime signals rather than just IV surface data.

## Known failure modes

- Payment not processed — 402 response if x402 payment header is missing or incorrect
- Rate limit exceeded — too many calls in a short window
- Stale data — options data may be cached and lag real-time Deribit feeds during high-volatility periods
- Service unavailable — 503 if upstream options data source is down
- Empty or null gamma ladder — occurs when options open interest data is insufficient

## How this service works

Returns BTC options gamma exposure analytics, including gamma ladder, gamma flip level, max pain, expected move, and related market regime signals.

## Output

Returns a structured JSON payload containing the BTC gamma ladder (GEX by strike), the gamma flip price level (the strike at which dealer gamma exposure transitions from positive to negative), the max pain strike price, the options-implied expected move for BTC, and related market regime signals indicating whether the market is in a positive or negative gamma environment.
