Hyperliquid gRPC Streaming
Raw L1 Feeds, Typed Market Streams
Stream blocks, fills, order statuses, and book diffs straight from Hyperliquid nodes. Replay from any retained block or timestamp, filter by user or coin, and open 14 typed market streams over Protocol Buffers.
Raw Feeds vs Market Streams
Node Feeds with Replay
Seven feeds read from the files the Hyperliquid node writes to disk, plus generated order-book snapshots. Each record arrives in a shared envelope with block number and timestamp cursors when present.
- Blocks, fills, order statuses, raw book diffs, misc events, TWAP statuses, mempool transactions
- Inclusive replay from a block number or Unix-ms timestamp, then live tail. Order-book snapshots and mempool transactions take timestamp cursors only.
- Server-side filters on users and coins for fills, diffs, and statuses
- StreamFills from Tokyo: 163 ms p50, 194 ms p95 from block timestamp to delivery
- Unary lookups return one record per call
{"blockNumber": "1139998345", "events": [["0x15b3...", {"coin": "BTC", "px": "78631.0"}]]}Typed Live Streams
Fourteen streams with typed request and response messages. Stateful views open with a snapshot or current state, then send ordered updates. Trade and fill streams are live-only.
- L2 book up to 100 levels per side, BBO for up to 20 coins per subscription
- L4 book, typed order updates, and take-profit/stop-loss lifecycle
- Trades, all/user/builder/liquidation fills, candles from 1s to 1d
- Sequence numbers on incremental streams for gap detection
{"coin": "BTC", "blockNumber": "1140007989", "bids": [{"px": "78497", "sz": "2.59056", "n": 16}]}Connect in Three Steps
Download the contract
Fetch the published proto. It defines both services, every message, and the filter contract.
curl -fsSLo v3.proto https://www.dwellir.com/docs/hyperliquid/grpc/v3.proto
Generate client stubs
Generate from the exact proto version you call. Runnable Go, Python, and Node.js examples are on GitHub.
protoc --go_out=. --go_opt=Mv3.proto=./hlgateway \ --go-grpc_out=. --go-grpc_opt=Mv3.proto=./hlgateway v3.proto
Connect over TLS with your API key
Pass the key in the x-api-key metadata header on every RPC. Start with ListFeeds to see what the endpoint serves.
grpcurl -proto v3.proto \ -H "x-api-key: $DWELLIR_API_KEY" \ "$HYPERLIQUID_GRPC_ENDPOINT" \ hyperliquid_l1_gateway.v3.HyperliquidL1Gateway/ListFeeds
Every Feed and Stream
Raw feeds HyperliquidL1Gateway
Market streams MarketStreaming
Built for Resumable Consumers
Replay and Resume
Position any raw feed at a block number or timestamp. The endpoint replays the selected record and every retained record after it, then tails live data. Order-book snapshots position by timestamp only.
Server-side Filters
Filter fills, raw book diffs, order statuses, and TWAP statuses by users and coins before they leave the endpoint. AND across fields, OR within a field.
Published Contracts
The proto file is public. Connect over TLS with the x-api-key metadata header from any language with a gRPC toolchain.
Documented to the Action
Block payloads are decoded in the docs down to all 47 signed action types, from order and cancel to twapOrder, vaultTransfer, and evmRawTx.
