description: '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.'
