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 1 API on the APIs.io network: REST API. 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 46 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Securities & Market Data regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/0xarchive: open an issue to ask a question, or submit a pull request to add artifacts.

APIs 3

Individual APIs this provider publishes, each with its own machine-readable definition.

0xArchive REST API

Current and historical market data across Hyperliquid core, Spot, HIP-3, HIP-4, and Lighter. Direct market-data requests use X-API-Key.

0xArchive WebSocket API

Real-time subscriptions for supported Hyperliquid channels and historical replay for Hyperliquid and Lighter. Clients authenticate during the handshake with a bearer API key.

0xArchive Hosted MCP

Read-only market-data discovery and retrieval for MCP clients. Hosted MCP uses client-managed OAuth and requires no 0xArchive API key.
