## 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 laevitas-options-gex-term-structure-2be0b645
```

Example prompt: Show me the dealer gamma exposure term structure for BTC options on Deribit using hourly resolution, pulling the last 100 data points.

## When to prefer this

Use this endpoint when you need to analyze how dealer gamma exposure is distributed across different option expiration dates for crypto assets. Ideal for understanding hedging pressure, pinning risk, and volatility dynamics tied to specific expiries. Prefer over generic options flow endpoints when term structure analysis of GEX is specifically needed.

## Known failure modes

- Invalid exchange name returns empty data or error
- Unsupported resolution enum value causes validation error
- Start/end timestamps outside available data range return empty data array
- Missing or invalid API key or insufficient x402 payment returns 401/402
- Limit exceeding 1000 returns validation error
- Invalid instrument_name format returns no data

## How this service works

Professional market data API for crypto derivatives, spot markets, prediction markets, Hyperliquid HyperCore data, proprietary volatility surfaces, and analytics.

## Authentication

Use an API key for authenticated REST requests:

```http
X-API-Key: your-api-key-here
```

Most data endpoints also support x402 pay-per-request without an API key.

## Pagination

Paginated endpoints return the cursor at `meta.next_cursor`. Pass that value back as the `cursor` query parameter to fetch the next page.

## WebSocket Streaming

Real-time streams are documented at `/websocket`.

| Data | Channel pattern |
| --- | --- |
| Trades | `trades.{market}.{exchange}.{instrument}` |
| OHLC ticker | `ohlc.ticker.{market}.{exchange}.{instrument}.{timeframe}` |
| OHLCVT | `ohlc.vt.{market}.{exchange}.{instrument}.{timeframe}` |

Variables: `market` is one of `perpetuals`, `futures`, `options`, or `spot`; `timeframe` is one of `1m`, `5m`, `15m`, `1h`, `4h`, or `1d`.

## Quick Start

```bash
curl "https://apiv2.laevitas.ch/api/v1/futures/ohlcvt?exchange=deribit&instrument_name=BTC-PERPETUAL" \
  -H "X-API-Key: your-api-key-here"
