Data is served from Redis cache, populated by a background worker that replays fullnode volume events and periodically refreshes from the Hyperliquid API. Also accepts `type: "assetContext"` as an alias. ## OpenAPI ````yaml /live-data/openapi-rest.json post /info#metaAndAssetCtxs openapi: 3.0.3 info: title: Hypedexer Live Data — REST API version: 0.1.0 description: >- REST API for real-time Hyperliquid market data served from a local fullnode. All data is accessed through a single unified endpoint `POST /info` that dispatches based on the `type` field in the JSON body. ## Request types | Type | Description | Handled | |------|-------------|----------| | `metaAndAssetCtxs` | Asset context (funding, OI, prices) | Locally (Redis cache) | | `allMids` | Mid prices for all coins | Locally (Redis cache) | | `userFills` / `userFillsByTime` | Fills for a specific user | Locally (volume files) | | `allFills` | All fills globally | Locally (volume files) | | `trades` | Trade data | Locally (volume files) | | `l2Book` / `l2Books` | L2 order book snapshot | Locally | | `availableDates` | Available data dates | Locally | | `clearinghouseState` | Clearinghouse state (single/multi-user) | Locally with upstream proxy per user | | `meta`, `spotMeta`, `openOrders`, ... | Proxied to local Hyperliquid node | Proxied to upstream | ## Authentication Optional. When `API_KEY` is configured on the server, all requests must include: ``` Authorization: Bearer ``` ## Response format Most types return: ```json { "result": , "cursor": null } ``` `allMids` returns the result directly (not wrapped): ```json { "BTC": "66764.5", "ETH": "3421.2" } ``` Proxied types return the upstream response as-is. contact: name: Hypedexer servers: - url: https://api.hypedexer.com description: Production — Live fullnode data security: - BearerAuth: [] tags: - name: Health description: Service health and info. - name: Asset Context description: >- Real-time asset context data: funding, open interest, oracle/mark/mid prices, volumes.
