0xArchive
0xArchive is a replayable market-data archive for two decentralised perpetuals venues, Hyperliquid and Lighter, delivered as one REST API, one WebSocket API that carries both live subscriptions and historical replay on a single connection, bulk Parquet export, and a hosted MCP server. Hyperliquid coverage is split into four route families - core perpetuals, Spot, HIP-3 builder perps and HIP-4 binary outcome markets - each with its own symbol format and its own set of available data types. Beyond order books, trades, candles, funding, open interest and liquidations, the archive reconstructs order-level depth that the venues do not serve directly: L4 for the Hyperliquid families and L3 for Lighter. Access is unusually flat - every plan including Free reaches every route family, schema and served depth, and plans gate capacity and Free's rolling 30-day history window rather than route access. An agent can buy its own 30-day Build or Pro access with an x402 USDC payment on Base and receive an API key on settlement, with no human signup step.
0xArchive publishes 53 APIs on the APIs.io network, including Data Quality API, HIP-3 Builder Perps - Breadth API, HIP-3 Builder Perps - Candles API, and 50 more. Tagged areas include Market Data, Historical Data, Crypto, DeFi, and Perpetuals.
The 0xArchive catalog on APIs.io includes 1 event-driven AsyncAPI specification.
0xArchive’s developer surface includes developer portal, pricing, status page, changelog, support, authentication, CLI, and 47 more developer resources.
