About 0xArchive

# Market Data Infrastructure

0xArchive builds live and historical market data infrastructure for Hyperliquid and Lighter. Hyperliquid coverage spans core perps, Spot, HIP-3, and HIP-4 outcome markets, from checkpoint history to order-level depth, replay, and exports.

**April 2023** Hyperliquid history starts

**2 venue APIs** Hyperliquid + Lighter.xyz

**5 coverage scopes** Core, Spot, HIP-3, HIP-4, Lighter

**API + exports** Replayable routes and bounded files

Our story

## The archive started with a missing workflow.

0xArchive.io was born out of frustration. As developers building around Hyperliquid, we needed historical order book data for backtesting and research. The data existed in public S3 buckets, but accessing it required significant engineering effort.

The product work since then has been to turn that archive into public, repeatable tools: API routes, replay, exports, coverage checks, status context, and reference files that keep API clients, scripts, and docs pointed at the same routes.

Today, we serve quantitative researchers, data teams, and developers who are working across Hyperliquid core, Hyperliquid Spot, Hyperliquid HIP-3, Hyperliquid HIP-4, and Lighter.xyz. Our archive starts with April 2023 Hyperliquid history and expands into newer market families as they launch.

What we believe

## Infrastructure should make the data easier to trust.

### Coverage-first

Coverage starts with what can be replayed and checked: Hyperliquid core history from April 2023, plus newer Spot, HIP-3, HIP-4, and Lighter markets as coverage is added.

### Developer references

REST, WebSocket, SDK, CLI, MCP, OpenAPI, and llms.txt are treated as first-class ways to discover and use the archive.

### Operational checks

Stable schemas, current status visibility, and coverage checks for production systems that need consistency.

### Clear boundaries

See the venue taxonomy, access requirements, coverage windows, and export paths before you wire the API into a backtest or production system.
