# Laevitas Expired Options Expiries Analytics > Laevitas Expired Options Expiries Analytics 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 settlement-price data for expired crypto options expiries on a given market and currency, optionally filtered to a specific maturity date. ## Facts - Endpoint: POST https://apiv2.laevitas.ch/api/v1/analytics/options/expired_expiries/%7Bmarket%7D/%7Bcurrency%7D?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-expired-options-expiries-analytics-44719a93 - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_lyM4cDB7NJZu3HJUNjbnV 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-expired-options-expiries-analytics-44719a93 -d '' ``` Example prompt: Pull up the expired options expiry data for BTC on Deribit from Laevitas — I want to see the strike prices, mark prices, and index reference at settlement for all past maturities. ## When to prefer this Use this endpoint when you need historical settlement data for already-expired crypto options contracts on a specific exchange and currency pair — particularly for auditing, backtesting, or post-expiry analytics. Prefer this over live options endpoints when the focus is on past expiries rather than current open interest or implied volatility. ## Known failure modes - Invalid market or currency parameter returns an error or empty data array - Unknown maturity string returns no matching rows - Expired or missing API key returns 401 unauthorized - Insufficient credits (x402) results in 402 Payment Required - Market not covered by Laevitas returns empty or error response - Rate limit exceeded returns 429 ## 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 JSON object with a UTC Unix timestamp and an array of settlement rows, each containing the expiry date label (e.g. '29MAR24'), strike price, option type (call/put), mark price in the settlement currency, mark price in USD, retained position quantity, and the index reference price at expiry.
