# Laevitas Market Summary History > Laevitas Market Summary 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). Retrieves paginated historical time-series summaries of crypto derivatives and futures market activity across currencies and exchanges. ## Facts - Endpoint: POST https://apiv2.laevitas.ch/api/v1/market/summary-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-market-summary-history-9f5a1913 - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_Zp-dElPgJskCDOJ_gs4__ 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-market-summary-history-9f5a1913 -d '' ``` Example prompt: Pull me the derivatives_summary history for BTC on Laevitas from January 1, 2024 to March 31, 2024 with 1-day resolution, page 1, limit 100 rows. ## When to prefer this Choose this endpoint when you need paginated historical time-series data for crypto derivatives or futures market summaries — including perpetual contract aggregates, exchange-level activity totals, rolling liquidations, or spot realized volatility — across a defined date range. Prefer this over real-time endpoints when performing backtesting, trend analysis, or historical research. Use the series parameter to select between currency-level summaries (derivatives_summary, futures_alt_summary) or exchange-level aggregates (futures_exchange_activity, futures_global_activity). ## Known failure modes - Missing required fields (start, end, series) returns a validation error - Invalid series enum value returns 400 bad request - Exchange parameter provided for currency-only series (derivatives_summary, futures_alt_summary) causes error - Currency parameter provided for venue-only series (futures_exchange_activity, futures_global_activity) causes error - Requesting data older than 1 year without sufficient API credits or subscription returns 402 Payment Required - Invalid ISO-8601 timestamp format returns parsing error - Page number beyond total_pages returns empty items array - Unsupported resolution enum value returns 400 - Expired or invalid API key returns 401 Unauthorized ## 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 Returns a paginated JSON object with dataset_id, series name, metadata (total rows, page info, data availability/coverage, completeness), and an array of time-series items containing derivatives or futures summary metrics such as open interest, volume, realized volatility, and liquidations for the requested window and resolution. ## Request schema (JSON Schema) ```json { "type": "object", "required": [ "end", "start", "series" ], "properties": { "end": { "type": "string", "description": "Inclusive ISO-8601 timestamp, not an exclusive bound." }, "page": { "type": "integer" }, "limit": { "type": "integer", "description": "Rows per page; retained market-cap duplicates may produce more than one row per timestamp." }, "start": { "type": "string", "description": "Inclusive ISO-8601 timestamp with timezone, truncated to seconds." }, "series": { "enum": [ "derivatives_summary", "futures_alt_summary", "futures_exchange_activity", "futures_global_activity" ], "type": "string", "description": "derivatives_summary and futures_alt_summary summarize perpetual contracts of one currency; derivatives_summary adds aggregate spot realized volatility and the legacy truncated OI/volume ratio. futures_exchange_activity totals one venue across its dated futures and perpetuals; futures_global_activity is one venue across its dated futures with rolling 24h liquidations." }, "currency": { "type": "string", "description": "Currency series only: normalized legacy underlying currency, e.g. BTC.
