Access is prepaid, with no automatic renewal. [Buy a subscription](https://v3.laevitas.ch/profile/subscription/wallet) or read the [USDC subscription guide](/x402#subscriptions).\n\nThe subscription belongs to your signed-in Laevitas account; wallet sign-in does not require an email. Enterprise users generate an API key in V3 after activation. Plan and billing-period limits still apply. Subscription purchases are separate from API credit bundles.\n\nFor Claude MCP, add `https://apiv2.laevitas.ch/api/v1/mcp`, select **Sign in now → Register automatically**\nwith no custom headers, and authorize with your API key on the Laevitas page.\nDo not enter a client ID or secret manually. All OAuth clients require PKCE S256.\nConnection guide: [MCP setup](/mcp). CIMD / published client identity is not supported.\n\n| Resource | Path |\n| --- | --- |\n| OpenAPI JSON | `GET /openapi.json` |\n| x402 discovery | `GET /.well-known/x402` |\n| Changelog | `GET /api/v1/changelog` |\n| WebSocket docs | `GET /websocket` |\n\n## REST Surfaces\n\n| Surface | Examples |\n| --- | --- |\n| Instruments | Cross-market contract reference data |\n| Futures | OHLCVT, trades, tickers, orderbook, liquidations, carry |\n| Perpetuals | OHLCVT, trades, funding, open interest, orderbook, liquidations |\n| Options | OHLCVT, trades, Greeks, volatility, flow, dealer GEX |\n| Options Backtests | Strategy templates, asynchronous submission, status, combined results, cancellation |\n| Vol Surface | Proprietary surface snapshots, slices, strikes, term structure, risk |\n| Spot | OHLCVT, ticker, trades, volume, L2 orderbook, snapshots |\n| Predictions | Polymarket instruments, categories, trades, ticker history |\n| Hyperliquid - HyperCore | Node-derived fills, liquidations, positions, funding, TWAPs, resting orders, L2 books |\n| Analytics | Realized volatility and derived metrics |\n\n## Pagination\n\nBacktests are asynchronous jobs, not paginated market-data queries. Start with\n`GET /api/v1/options/backtests/strategies`, submit with `POST /api/v1/options/backtests`,\nthen poll `/{id}` and retrieve `/{id}/result`. These responses have no data/meta wrapper.\n\nPaginated endpoints return the cursor at `meta.next_cursor`.
