0xArchive is the historical and live market-data API for Hyperliquid and Lighter: route-addressed market data, replay and reconstruction context, Data Catalog exports, and quality metadata for Hyperliquid core, Hyperliquid Spot, HIP-3, HIP-4, and Lighter.
The binding 0xArchive Data License is incorporated into the Terms of Service. This page explains that policy for developers. If this page conflicts with the Data License or Terms, the Data License and Terms control.
Data rights decide what your system can do after an endpoint, export, SDK, CLI job, MCP tool, or Skill returns 0xArchive Data. API access does not by itself grant the right to resell the data as a standalone feed. Treat raw-data redistribution as a commercial/legal boundary, not a code-generation detail.

​
Practical Rule

You may use 0xArchive Data for internal and commercial purposes inside your business and products. Ordinary products and outputs are permitted when they materially transform the source data and do not expose original records or allow them to be reasonably reconstructed. Written permission is required for benchmarks, indices, financial products, standalone or substitute market-data products, raw redistribution, and white-label or OEM data delivery.

​
What Requires Written Permission

Contact 0xArchive before doing any of the following:
  • Reselling raw 0xArchive records
  • Publishing bulk copies or downloadable data dumps
  • Mirroring or passing through the 0xArchive API
  • Operating a substitute historical or live market-data feed
  • Creating benchmarks, indices, or financial products
  • Publishing an output that exposes original records or allows them to be reasonably reconstructed
  • White-label or OEM delivery where access to the data itself is the product
Using 0xArchive as a replay data source for Hyperliquid and Lighter does not by itself restrict a product. Charts, analysis, alerts, model outputs, indicators, and ordinary customer-facing products are permitted when they materially transform the source data and do not expose original records or allow them to be reasonably reconstructed. Benchmarks, indices, financial products, standalone or substitute market-data products, raw redistribution, and white-label or OEM data delivery require prior written permission.

​
Data Downloaded Before Cancellation

Cancellation or termination ends future access when the account entitlement expires. You may retain and continue using 0xArchive Data downloaded while the account was entitled to access it, subject to the Data License. Future updates, support, and access are not included after entitlement ends.

​
Keep Source Context Attached To Data

Every stored dataset should carry enough context to show where it came from. Save the route, symbol, venue family, time window, query parameters, cursor chain, meta.request_id, freshness or quality state, and generation time alongside the payload. For Data Catalog exports, also store the job ID, schema keys, quote context, credits applied, and file format. That metadata makes a file useful to another engineer later and gives support enough context to diagnose an issue. For example, a historical trades pull should store more than the rows:

​
Data Catalog Exports

The Data Catalog is the file-first path for market history. It supports one-off historical analysis, offline notebooks, model training inputs, and product workflows. Use the quote and checkout flow when the job is a file purchase. Use the API when the job needs repeatable programmatic access. Keep the market family, symbol, schema keys, date range, quote context, credits applied, delivery format, generation time, and relevant quality notes with each export. Credits reduce checkout cost; they do not change redistribution rights.

​
Automation Guidance

Coding agents, CLI jobs, notebooks, and MCP clients can write pull scripts, add request-ID logging, check freshness, and save reproducible metadata. Keep redistribution decisions outside generated code. A script should not turn a private workflow into a public raw-data product or invent permission language.

​
Next Steps

Start with Historical market data for bounded pulls, Point-in-time backtesting for reproducible strategy research, and Rate limits and credits for plan capacity. Use Contact for benchmark, index, financial-product, standalone or substitute market-data, raw-redistribution, white-label, or OEM rights.
