# Hydromancer Vs 0xArchive

> For Hyperliquid and Lighter market data, live and historical, 0xArchive returns every order, trade, and fill across both venues from one API and key.

Every order, trade, and fill on Hyperliquid and Lighter, live and historical, from one API. 0xArchive is the historical and live market-data API for Hyperliquid and Lighter: order-level depth, order lifecycle, and per-trade attribution across both venues, returned as normalized JSON from one key.

One call returns order books, trades, candles, funding, open interest, liquidations, and order-level (L4) depth. Hyperliquid order books and trades go back to April 2023; order-level depth and lifecycle since March 2026; Lighter trades since August 2025 with L3 depth since March 2026. No collectors, no backfill, no rebuilding the book.

## What One Key Returns

| Market-data job                                   | 0xArchive                                                                                   |
| ------------------------------------------------- | ------------------------------------------------------------------------------------------- |
| Hyperliquid order books (L2), live and historical | 20-level snapshots about every 1.2 seconds since April 2023, 24.6B+ records, 176 symbols    |
| Order-level depth (L4) and lifecycle              | Every order add, fill, cancel, and TP/SL, with wallet attribution, since March 2026         |
| Hyperliquid families                              | Core perps, Spot, HIP-3, and HIP-4, each its own route family with its own history          |
| Lighter                                           | Trades, funding, and open interest since August 2025; L3 order-level depth since March 2026 |
| Trades, funding, open interest, liquidations      | Hyperliquid since April 2023 (liquidations since December 2025), Lighter since August 2025  |
| Live stream and replay                            | WebSocket subscriptions and exact-window replay on one socket                               |
| Coverage, freshness, incidents, latency, gaps     | One data-quality surface across every supported family                                      |

## Where Hydromancer Fits

0xArchive sells bounded market-data routes, not builder-platform operations; that operational layer is Hydromancer's. Its site lists a builder REST API with batch endpoints such as `builderFillsByTime` and `builderLiquidations` that query 1,000+ wallets at once, WebSocket streaming for fills and orders, L2 and L4 order-book streaming with address visibility, and Reservoir, a free Parquet-on-S3 archive of Hyperliquid historical data. Paid tiers run $300 to $2,500 a month with an uptime SLA, and more than 80 apps build on it. When the job is builder-platform tooling, builder-fill analytics, or a free S3 corpus to explore, Hydromancer owns that job, and 0xArchive is not the right fit for it; this API is the archive layer underneath, the records rather than the platform.

Hydromancer covers one venue. When the same job also needs Lighter, or needs a bounded REST route with a stated historical window instead of a bucket to crawl, the decision moves here.

## When To Use 0xArchive

One key spans both Hyperliquid and Lighter, with the deepest layer of each: full order-level (L4) depth and lifecycle on the Hyperliquid families since March 2026, L3 order-level depth on Lighter since March 2026, every order add, fill, cancel, and TP/SL carrying wallet attribution. The market data comes back normalized, with named fields, live or historical: more than 24 billion Hyperliquid order-book records and trades back to April 2023. Every response carries a request ID and a data-quality path you can check before a backtest trusts the window. Every route, market family, and schema is available on every tier, including Free. Every order, trade, and fill. One API.

## Run One Route

```bash theme={"theme":"github-dark"}
curl "https://api.0xarchive.io/v1/hyperliquid/orderbook/BTC/history?limit=1" \
  -H "X-API-Key: $OXARCHIVE_API_KEY"
```

## Next Step

Start with [Venue coverage](/venue-coverage), run one request against [Hyperliquid REST](/rest-api/hyperliquid), then add [Data quality](/data-quality).
