## 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-historical-futures-settlement-funding-rate-648078ca -d '<json body>'
```

Example prompt: Pull the historical settlement funding rates for BTC perpetual futures on Binance from January 1, 2024 to March 31, 2024, page 1 with 50 rows per page.

## When to prefer this

Choose this endpoint when you need time-series historical funding rate data for crypto perpetual or futures contracts, especially for backtesting, carry trade analysis, or academic research. Prefer this over real-time funding rate feeds when you need data spanning weeks, months, or years rather than the current snapshot. It supports paginated access, making it suitable for bulk data extraction across long periods.

## Known failure modes

- Missing required 'start' parameter returns a 400 validation error
- Invalid market or symbol path parameter may return 404 or empty items array
- Date range too broad without pagination may return partial data or require multiple pages
- Expired or invalid API key returns 401 unauthorized; insufficient credits return 402 Payment Required
- Rate limiting may return 429 Too Many Requests for high-frequency callers

## 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
```

Data and history endpoints also accept x402 without an API key: 1, 5 or 10 credits ($0.001 each) for data up to 1 year, 1–3 years or older.

**Subscriptions with USDC:** Premium and Enterprise can be purchased on Base or Solana for a month, a quarter, six months or a year. Access is prepaid, with no automatic renewal. [Buy a subscription](https://v3.laevitas.ch/profile/subscription/wallet) or read the [USDC subscription guide](/x402#subscriptions).

The subscription belongs to your signed-in Laevitas account; wallet sign-in does not require an email. Enterprise users generate an API key in V3 after activation. Plan and billing-period limits still apply. Subscription purchases are separate from API credit bundles.

## 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 |
| Options Backtests | Strategy templates, asynchronous submission, status, combined results, cancellation |
| 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

Backtests are asynchronous jobs, not paginated market-data queries. Start with
`GET /api/v1/options/backtests/strategies`, submit with `POST /api/v1/options/backtests`,
then poll `/{id}` and retrieve `/{id}/result`. These responses have no data/meta wrapper.

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`.

## Output
