Returns paginated OHLCV candlestick history for a retained spot trading pair on a specified exchange over a given time range and resolution. ## Facts - Endpoint: POST https://apiv2.laevitas.ch/api/v1/spot/candle-history?utm_source=zero.xyz - Price: $0.1/call - Payment: x402 - Status: unknown - Last checked: 2026-10-31 - Activations on Zero: 0 - Tags: x402 - Canonical page: https://www.zero.xyz/c/laevitas-spot-candle-history-558a8c11 - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_3Itb1Gj0lbxEz1bFws3jj 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-spot-candle-history-558a8c11 -d '' ``` Example prompt: Pull 1-hour candle history for BTC-USDT on Coinbase from January 1, 2025 to January 31, 2025, showing 100 candles per page, using the Laevitas spot candle history endpoint. ## When to prefer this Use this endpoint when you need structured historical OHLCV candlestick data for a specific crypto spot pair on a supported exchange, especially for backtesting, charting, or time-series analysis. It supports multiple resolutions from 1-minute to 1-day, handles pagination for large date ranges, and provides coverage metadata so you know exactly how far back data is available. Prefer this over generic market data providers when you need reliable, professionally curated spot candle data with clear pagination controls and coverage transparency. ## Known failure modes - Invalid or unsupported exchange name returns an error or empty coverage - Instrument name not found or not retained for the exchange - start or end not valid ISO-8601 with timezone causes validation error - Resolution value not in allowed enum causes bad request - Requested date range has no data coverage (empty_reason field populated) - Page number beyond total_pages returns empty items array - Limit exceeding 1440 causes a validation error - Expired or missing API key / insufficient x402 credits returns 401/402 ## 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.

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`. ## 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 A paginated JSON object containing: an array of OHLCV candle rows for the requested spot pair, resolution, and time range; pagination metadata (total rows, current page, total pages, limit, count basis); and data availability/coverage details including the earliest and latest observed timestamps for the instrument on the exchange. ## Request schema (JSON Schema) ```json { "type": "object", "required": [ "end", "start", "exchange", "resolution", "instrument_name" ], "properties": { "end": { "type": "string", "description": "Inclusive ISO-8601 instant with timezone, truncated to seconds.
