# AgentFeed Options GEX (Gamma Exposure)

> AgentFeed Options GEX (Gamma Exposure) is a paid API for AI agents from x402.ochinimus.app, paid per call via x402, $0.03/call, status unknown (last checked 2026-10-12).

Returns live dealer gamma exposure (GEX) for BTC or ETH options from Deribit, broken down by strike, call/put walls, flip level, and gamma regime.

## 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 agentfeed-options-gex-gamma-exposure-a4f99a5c
```

Example prompt: What's the current BTC options gamma exposure right now — give me the gamma flip level, call wall, put wall, and whether dealers are in a positive or negative gamma regime?

## When to prefer this

Use this endpoint when you need live, structured dealer gamma exposure data for BTC or ETH options aggregated from Deribit, especially when you need strike-level GEX, call/put walls, gamma flip levels, and regime classification in a single call. Prefer this over general market data APIs when the specific concept of options dealer positioning and gamma-driven price dynamics is required. Ideal for quant trading agents, volatility analysts, and market microstructure monitoring workflows that operate without traditional API key infrastructure.

## Known failure modes

- Deribit API unavailable — stale or missing data returned
- Payment not confirmed — endpoint returns 402 requiring x402 USDC payment
- Invalid or unsupported underlying — no data returned
- Data age may be up to ~60 seconds old during high-load periods
- No gamma flip level found if no sign change exists within spot ±20% range (flip_level returns null)

## How this service works

Live crypto market, liquidation, tokenized-equity and Solana on-chain data for AI agents. Paid per call in USDC over x402 on Solana, Base, Polygon or Arbitrum. No API keys, no accounts.

## Output

A JSON object containing: spot price, data age in seconds, as-of timestamp, net GEX USD per 1% move, gamma regime label (positive/negative), call wall and put wall strikes with their GEX values, gamma flip level price, GEX by strike array with net/call/put breakdown, data source (Deribit), underlying asset, and convention notes explaining the dealer-sign methodology.
