0xArchive provides historical and live market-data records for Hyperliquid and Lighter through one API. Coverage depends on venue family, data type, symbol, and time window. Velo Data is a trader-facing analytics UI for reading heatmaps, CVD, and desk-style charts. For the underlying market data, the kind you store, backtest, and feed to a model or agent, you call 0xArchive.
One key returns order books, trades, candles, funding, open interest, liquidations, and full order-level (L4) depth as normalized JSON, live or historical. Order books and trades go back to April 2023; L4 order-level history from March 2026 on core and HIP-3, and from May 2026 on HIP-4; Spot order events and reconstructable checkpoints require separate coverage checks; lifecycle history is route-specific. 0xArchive removes venue collection and historical backfill work; supported reconstruction routes return a checkpoint/snapshot. A snapshot-only consumer can use that state directly. A continuously updated local L4 book still must apply ordered diffs or replay, detect gaps, and reconstruct state after the checkpoint; the API does not remove those local-state obligations.
Evidence checked August 28, 2026. This page limits the Velo comparison to the trader-analytics category named in the title. No current first-party authority note was retained for Velo’s venue coverage, resolution, pricing, history, or delivery terms; those details are not asserted below. The 0xArchive route and window claims use Hyperliquid L4, Lighter L3, and Venue coverage.
What One Key Returns
Where Velo Data Fits
0xArchive is not the right fit when a trader-facing analytics screen is the deliverable. This comparison does not make a current claim about Velo’s venue coverage, resolution, pricing, retention, or delivery terms because the current first-party source set is not specific enough to support those details. Use 0xArchive when the workflow needs route-addressed Hyperliquid or Lighter records for storage, backtesting, replay, models, or agents.
The deciding question is the output: a chart is not the same artifact as route-addressed records. Use 0xArchive when the downstream system must store, replay, or parse the market data.
When To Use 0xArchive
0xArchive runs collection, backfill, and reconstruction server-side and returns a checkpoint/snapshot. If your application keeps a continuously updated local book, apply ordered diffs/replay after that checkpoint; a snapshot-only consumer can use the returned state directly. The market data comes back normalized, with named fields, live or historical: order-book records and trades back to April 2023, plus full order-level L4 history with wallet attribution from March 2026 on core and HIP-3, and from May 2026 on HIP-4; Spot order events and reconstructable checkpoints require separate coverage checks. Lighter L3 starts in March 2026. Store the request ID when the response exposes it, and check data quality before a backtest trusts the window. When the output has to become rows in a warehouse, inputs to a model, a replayable backtest, an API-backed feature, or a coding-agent task, you build on the data, not on a screenshot of it. Plans govern capacity and request windows. Availability is specific to the route, family, symbol, and schema; inspect the selected operation and coverage before relying on it. Agents reach the same routes through the hosted MCP server at https://mcp.0xarchive.io/mcp.
