0xArchive is a market-data API and archive for Hyperliquid and Lighter. Use documented venue routes for current and historical data, supported WebSocket channels and replay for streams, or Parquet exports for bulk history.

Start with your venue, market, and data type. The available route and history window depend on that exact combination.

Developers put market data into applications and monitoring systems. Quantitative researchers query or replay historical data for backtests. Data teams export Parquet files for notebooks and warehouses.

Choose the smallest useful path first: a REST query for a bounded window, a supported WebSocket channel for a stream, or an export for a larger historical dataset.

Coverage includes Hyperliquid core perpetuals, Spot, HIP-3 builder markets, and HIP-4 outcomes, plus Lighter in its own venue family. Depending on the market, available data includes order books, trades, candles, funding, open interest, and order-level records. Hyperliquid L4 and Lighter L3 are distinct datasets, not interchangeable depth labels.

Check the exact symbol, schema, coverage dates, and freshness before using a dataset. Free API requests and replays reach the most recent rolling 30 days, with a 30-day maximum span; Build and above can query the full retained archive where that dataset exists.

Use REST for current reads and bounded historical queries. Use WebSocket for supported live subscriptions or historical replay; live and replay availability varies by channel. Check the channel matrix for the exact market family before building around a stream.

For a bulk historical pull, choose a market, data type, and UTC date range in the Data Catalog, then download a ZSTD-compressed Parquet file. The catalog shows coverage and the export estimate before checkout.
