## 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 adh-options-gamma-exposure-gex-signal-b58ace21
```

Example prompt: What's the current gamma exposure situation for SPY — tell me the gamma flip level, whether dealers are in positive or negative gamma, and where the call wall and put wall are sitting right now.

## When to prefer this

Choose this endpoint when you need derived, ready-to-use dealer gamma exposure analytics rather than raw option chain data. It is ideal for volatility regime classification, identifying gamma flip levels, locating call/put walls for support/resistance analysis, and understanding dealer hedging dynamics — all computed from live option chains across multiple expirations. Prefer it over raw broker option chain feeds when you want pre-computed GEX metrics with regime labeling and educational context included.

## Known failure modes

- No option chain data available for requested symbol — empty symbols array returned
- Stale data if live option chain feed is delayed or unavailable
- Payment failure via x402 protocol — 402 response if USDC settlement not completed
- Truncated profile data if option chain is very large
- Symbol not supported — not all US equities may have option chains processed
