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`.

Output
Returns a JSON object with a 'data' array containing Level 1 perpetual futures market records (bid/ask, trade data, timestamps, or OHLC bars depending on query), a 'success' boolean, and possibly a pagination cursor for subsequent pages.
Example use cases
Risk monitoring for leveraged positions
“Fetch me the current bid-ask spreads for ETH-PERPETUAL and BTC-PERPETUAL across Binance, OKX, and Deribit right now so I can compare liquidation risks before entering.”
Arbitrage opportunity detection
“Give me the last 4 hours of 15-minute OHLC data for SOL-PERPETUAL on Bybit and Hyperliquid so I can spot price divergences between exchanges.”
Backtest funding rate correlations
“Pull daily OHLCVT data for BTC-PERPETUAL and ETH-PERPETUAL on Deribit for the entire month of November 2023 so I can analyze how their funding rates moved together.”
Technical details
Endpoint
GEThttps://apiv2.laevitas.ch/api/v1/perpetuals/level1When to prefer
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.
