## 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-perpetuals-level-1-market-data-3a96887f
```

Example prompt: Pull the last 100 hourly Level 1 market data points for BTC-PERPETUAL on Deribit from Laevitas — starting from 2024-01-01 through 2024-01-07, with 1h resolution.

## When to prefer this

Use this endpoint when you need top-of-book (Level 1) price data — bids, asks, or OHLC snapshots — specifically for perpetual futures instruments across major crypto exchanges like Binance, OKX, Deribit, Bybit, or Hyperliquid. Prefer it over WebSocket channels when you need historical or paginated data rather than a live stream. Choose it over spot or options endpoints when your instrument is a perpetual swap contract.

## Known failure modes

- Missing or invalid API key returns 401 Unauthorized
- Unsupported exchange name returns empty data or 400 error
- Invalid instrument_name returns empty data array
- Resolution enum value not in allowed set returns validation error
- Limit exceeds 1000 returns validation error
- Invalid date range (start after end) may return empty data or error
- x402 payment not provided or insufficient returns 402 Payment Required

## 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.

| Resource | Path |
| --- | --- |
| OpenAPI JSON | `GET /openapi.json` |
| x402 discovery | `GET /.well-known/x402` |
| Changelog | `GET /api/v1/changelog` |
| WebSocket docs | `GET /websocket` |

## 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 |
| Predictions | Polymarket instruments, categories, trades, ticker history |
| 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`.
