# DripMetrics BTC Options GEX (Gamma Exposure)

> DripMetrics BTC Options GEX (Gamma Exposure) is a paid API for AI agents from api.dripmetrics.ai, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-11).

Returns the full strike-level gamma exposure profile, total net GEX, and gamma flip level for BTC options derived from the Deribit option chain

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 dripmetrics-btc-options-gex-gamma-exposure-7c17d752
```

Example prompt: What's the current BTC gamma exposure profile on Deribit — I want to see the strike-level GEX breakdown, total net GEX, and where the gamma flip level sits right now.

## When to prefer this

Use this endpoint when you need on-demand, trade-level BTC gamma exposure metrics derived directly from the live Deribit option chain, without requiring a subscription or API key. Prefer this over generic crypto data APIs when you specifically need GEX, the gamma flip level, or strike-level open-interest-weighted Black-76 gamma for Bitcoin options. Ideal for agents operating in pay-per-call workflows via x402.

## Known failure modes

- Payment failure: x402 payment not processed or insufficient USDC balance returns a 402 error
- Deribit data unavailable: if the underlying Deribit option chain is unreachable, the API may return an error or null value
- Rate or quota issues: repeated calls without valid payment headers may be rejected
- Stale data: computedAt timestamp may lag real-time if upstream chain data is delayed
- Empty option chain: if no open interest exists for queried strikes, components may be sparse or null

## How this service works

DripMetricsAI (https://dripmetrics.ai/) provides on-demand BTC option-derived metrics that combine the Deribit option chain with DripMetrics' own trade-level realized calculations. Agents can pay per request via x402 and receive structured JSON metrics without subscriptions or API keys. GEX aggregates open-interest-weighted Black-76 gamma across the whole Deribit BTC chain into a strike-level gamma exposure profile, total net GEX, and the gamma flip level.

## Output

A structured JSON object containing: the metric name (GEX), the BTC pair label, a total net GEX value, a components object with strike-level gamma exposure data, sample size details, the data source (Deribit), and a computedAt timestamp indicating when the metrics were calculated.
