The 24 h reference is Hyperliquid's previous-day price from the latest snapshot; the 7 and 30 day references are the hourly snapshot marks at or before then. Markets without a snapshot in the last 3 hours are left out. Pricing: base + per row + node reads. Scope: `markets:read`. ## OpenAPI ````yaml /data-api/openapi.json get /v1/markets/price-changes openapi: 3.1.0 info: title: Hyperdash Data API version: v1 description: >- Hyperliquid data from Hyperdash's own nodes.
