# Laevitas Vol Surface Risk Decompose

> Laevitas Vol Surface Risk Decompose is a paid API for AI agents from apiv2.laevitas.ch, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-16).

Decomposes portfolio risk across proprietary volatility surface dimensions for crypto options positions

## Facts

- Price: $0.1/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-16

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 laevitas-vol-surface-risk-decompose-c0cfb0fc -d '<json body>'
```

Example prompt: Can you decompose the vol surface risk for my crypto options positions — here are the positions: '[{"instrument":"BTC-27JUN25-100000-C","quantity":10},{"instrument":"BTC-27JUN25-90000-P","quantity":-5}]'?

## When to prefer this

Use this endpoint when you need to understand how a crypto options portfolio is exposed to different components of the volatility surface — such as level risk (vega), skew risk, term structure risk, and convexity — using Laevitas's proprietary vol surface model. Prefer this over generic Greeks endpoints when you need a structured risk decomposition rather than raw Greeks values.

## Known failure modes

- Invalid or malformed positions string returns error
- Unsupported instrument identifiers cause lookup failure
- Empty positions input returns empty or error response
- Authentication failure if API key missing and x402 payment not completed
- Rate limiting if quota exceeded

## 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.

## REST Surfaces

| Surface | Examples |
| --- | --- |
| Instruments | Cross-market contract reference data |
| Futures | OHLCVT, trades, tickers, orderbook, liquidations, carry |
| Perpetuals | OHLCVT, trades, funding, open interest, orderbook, liquidations |
| Options | OHLCVT, trades, Greeks, volatility, flow, dealer GEX |
| Vol Surface | Proprietary surface snapshots, slices, strikes, term structure, risk |
| Spot | OHLCVT, ticker, trades, volume, L2 orderbook, snapshots |

| Hyperliquid - HyperCore | Node-derived fills, liquidations, positions, funding, TWAPs, resting orders, L2 books |
| Analytics | Realized volatility and derived metrics |

## 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"
```

## Output

Returns a JSON object with a 'data' field containing the decomposed risk breakdown across proprietary volatility surface dimensions (e.g. level, skew, term structure, convexity risk components), along with a 'success' boolean indicating whether the computation succeeded.
