About 0xArchive

# The archive behind replayable market data.

0xArchive provides replayable market data across Hyperliquid core, Hyperliquid HIP-3, Hyperliquid HIP-4 outcome markets, and Lighter.xyz, from checkpoint history to order-level depth.

**April 2023** Hyperliquid history starts

**4 venue families** Hyperliquid, HIP-3, HIP-4, Lighter

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

Our story

## The archive started with a missing workflow.

0xArchive.io was born out of frustration. As traders and developers building on 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.

We realized that if we needed this data, others did too. So we built the infrastructure to ingest, process, and serve this data through a simple API. What started as an internal tool is now available to everyone.

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

What we believe

## Infrastructure should make the data easier to trust.

### Data First

We ship deep historical coverage where it exists, from April 2023 Hyperliquid history to newer HIP-3, HIP-4 outcome, and Lighter markets as they go live.

### Developer Experience

Self-serve API access, transparent pricing, and comprehensive documentation. Get your API key in under 2 minutes, not 2 weeks.

### Reliability

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

### Community Driven

We listen to our users and build what the community needs. Your feedback shapes our roadmap.

Start self-serve
