Stream demo

What the streams look like

Trades, depth, and throughput rendering in your browser using simulated data in the documented stream shape. Every panel is annotated with the gRPC method that produces it in production, so what you see here maps directly to what a real key delivers.

The meter counts at the production feed's nominal trade rate (derived from 6.5M+ trades a day); the visible tape renders a capped sample of it: at most ten rows a second, never the full firehose. All panels on this page replay simulated data in the documented stream shape.

What you are looking at

Every panel is one gRPC method

The data above is simulated; the methods are not. With a real key, these exact commands stream the production feed: same fields, same exact-decimal strings, same ordering guarantees.

Trade tape

hyperliquid_swaps.v1.SwapStreaming/StreamSwaps

Every fill on BTC: side, exact-decimal price and size, notional, maker/taker role, and the trader's wallet on each row. Filter server-side to the coins you need.

grpcurl -H 'x-api-key: YOUR_KEY' \  -d '{"market_type":"ALL","coins":["BTC"]}' \  stream.hyperliquidrpc.com:443 \  hyperliquid_swaps.v1.SwapStreaming/StreamSwaps

Depth ladder

hyperliquid.OrderBookStreaming/StreamL2Book

Never-crossed L2 for BTC, twelve levels a side with per-level order counts, one update per block. Set n_levels to the depth your strategy actually reads.

grpcurl -H 'x-api-key: YOUR_KEY' \  -d '{"coin":"BTC","n_levels":12}' \  stream.hyperliquidrpc.com:443 \  hyperliquid.OrderBookStreaming/StreamL2Book

Session meter

client-side counters, no subscription

Messages received, instantaneous rate, and session uptime are counted in your browser at the nominal feed rate. In production you would read the same truth from your consumer's own counters. The stream carries monotonic sequence numbers, so gaps are detectable, not silent.
