# Laevitas Options Instrument Volume History > Laevitas Options Instrument Volume History is a paid API for AI agents from apiv2.laevitas.ch, paid per call via x402, $0.1/call, status unknown (last checked 2026-10-31). Returns paginated historical trading volume data for a specific crypto options instrument on a given exchange over a requested time range. ## Facts - Endpoint: POST https://apiv2.laevitas.ch/api/v1/options/instrument-volume-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-options-instrument-volume-history-89368f9d - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_oaAFiUad3Ey-8CVLApboy 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-options-instrument-volume-history-89368f9d -d '' ``` Example prompt: Pull the historical volume data for BTC-25DEC26-100000-C on Deribit from January 1 2025 to March 31 2025, showing 100 rows per page starting at page 1. ## When to prefer this Use this endpoint when you need granular, paginated historical trading volume for a specific named options contract (e.g. BTC-25DEC26-100000-C) on a supported exchange (Deribit, OKX, Binance, Bybit, Paradex). It is the right choice for backtesting liquidity, analyzing how active a specific strike/expiry was over a time window, or building time-series volume charts for a known instrument. Prefer it over aggregated or cross-instrument endpoints when the exact contract identifier is known and per-instrument granularity is required. ## Known failure modes - Invalid instrument_name format (must be CURRENCY-EXPIRY-STRIKE-TYPE, e.g. BTC-25DEC26-100000-C) returns a validation error - Unsupported exchange value outside the allowed enum returns a validation error - Missing required fields (start, end, exchange, instrument_name) returns a 400 error - Date range with no data available returns empty items with coverage metadata explaining the gap - Page number beyond total_pages returns an empty result set - Invalid ISO-8601 datetime format for start or end returns a parsing error - Insufficient credits or expired subscription returns a 402 payment required error ## 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 historical volume rows for the specified options instrument, with each row representing a bucket-direction pair (trade timestamps and volumes).
