Hyperliquid and Lighter books, fills and funding
What it is
A hosted archive of Hyperliquid and Lighter market data, exposed over REST, WebSocket, webhook alerts and downloadable exports. Snapshot routes return order books, fills, funding, liquidation events and public positions by wallet or market, and the socket can stream live events or replay a past window. Trading developers and researchers who want those two venues, including people wiring an assistant through the MCP server, are the audience. REST, the socket and the Python, TypeScript and Rust clients all require an API key, coverage is judged per symbol rather than for a whole venue, and bulk files are a separate purchase.
