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`. ## 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' array containing carry metrics (funding rate vs basis) for the specified perpetual instrument, exchange, and time range, plus a 'success' boolean flag.
Example use cases
Monitor funding arbitrage opportunities across exchanges
“Compare the carry spreads between BTC perpetuals on Binance, OKX, and Bybit over the last 7 days. Show me which exchange has the highest funding rate basis right now and where the best arbitrage gaps are.”
Analyze historical carry trends for trading decisions
“Get me the daily carry data for ETH perpetuals on Deribit going back 3 months. I need to see how the basis-funding spread has evolved to decide if it's a good time to enter a carry trade.”
Track volatility and carry correlation patterns
“Pull perpetuals carry metrics for both BTC and ETH on Hyperliquid for the past month with 4-hour candles. I want to see if carry spreads move together or diverge during different market conditions.”
Technical details
Endpoint
GEThttps://apiv2.laevitas.ch/api/v1/perpetuals/carryWhen to prefer
Use this endpoint when you need historical or recent carry (funding rate vs basis) data specifically for perpetual futures contracts on crypto exchanges like Binance, OKX, Deribit, Bybit, or Hyperliquid. Prefer this over generic market data APIs when the analysis involves carry trades, funding arbitrage, or basis-funding spread analysis in crypto derivatives.
