## 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-gex-options-analytics-api-x402-898a59ee
```

Example prompt: What's the current gamma exposure ladder, max pain strike, and gamma flip level for BTC options from Kronos right now?

## When to prefer this

Use this endpoint when you need structured, ready-to-consume crypto options market data (GEX, max pain, gamma flip, expected move) for BTC or ETH without building your own Deribit integration. Prefer this over raw exchange APIs when you want pre-computed dealer gamma metrics in a single call. The x402 micropayment model ($0.04/call) makes it cost-effective for on-demand agent queries rather than bulk subscriptions.

## Known failure modes

- Payment not received or x402 handshake fails — endpoint returns 402 Payment Required
- Unsupported asset symbol — endpoint may return 400 or empty/unavailable response
- Deribit data unavailable — response may include available:false flag
- Stale data if options market is closed or low-liquidity period
- Malformed asset path parameter causes routing error
