Coverage: April 2024 to February 2026 from our market data archive (`data_source: archive`, top ~20 levels per side), and continuously since 23 September 2026 from the full order book replayed from our own Hyperliquid node (`data_source: node`, every resting order). No book data between 10 February and 23 September 2026. Returns 404 when no book exists for the coin in the 24 hours before `at`. ## OpenAPI ````yaml /api-reference/openapi.json get /market/book/{coin} openapi: 3.0.3 info: title: 'Hypedexer API: Indexed Data' version: 1.0.0 description: >- API to query indexed Hyperliquid trading data.
