# Laevitas Perpetuals Instrument History Discovery > Laevitas Perpetuals Instrument History Discovery 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). Discovers historical perpetual contract names observed on a given exchange/currency/date, or retrieves observation bounds for a specific contract. ## Facts - Endpoint: POST https://apiv2.laevitas.ch/api/v1/perpetuals/instrument-history/discovery?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-perpetuals-instrument-history-discovery-2885c4f2 - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_ZZkUMpw-mTV7mVrFQpEel 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-perpetuals-instrument-history-discovery-2885c4f2 -d '' ``` Example prompt: Using Laevitas, find all BTC perpetual contract names that were observed on Binance on 2024-01-15, using instruments mode with a page size of 100. ## When to prefer this Use this endpoint when you need to discover which perpetual contract names existed on a specific exchange at a point in time, or when you want to know the exact observation date range for a named perpetual instrument before fetching its full history. It is the right starting point when you don't yet know the exact instrument name or when you need to enumerate all available perps for a currency/exchange/date combination before calling the instrument-history endpoint. ## Known failure modes - Missing required fields (mode, currency, exchange) returns validation error - Invalid exchange value not in enum returns 400 - instrument_name required for coverage mode but not provided returns error - date required for instruments mode but missing returns error - No matching history for the given exchange/currency/date returns empty data array - Invalid cursor or mismatched pagination parameters returns 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 Returns an array of perpetual instrument records, each containing the exact contract name, the first and last timestamps it was observed, and a retrieval object with the path and parameters needed to fetch its full historical data. Also includes pagination metadata with a next_cursor for continuing large result sets. ## Request schema (JSON Schema) ```json { "type": "object", "required": [ "mode", "currency", "exchange" ], "properties": { "date": { "type": "string", "description": "Required only for instruments: YYYY-MM-DD UTC day to search, not an expiry or a trading-status date." }, "mode": { "enum": [ "instruments", "coverage" ], "type": "string", "description": "instruments finds contract names observed on a UTC day. coverage reports retained observation bounds for one exact currency and contract." }, "limit": { "type": "integer", "description": "instruments page size, default 100, maximum 500.
