When to use which surface

​

Critical rules

1. Info API endpoint URL - https://hypercore.goldrushdata.com/info (note: hypercore, not hyperliquid).
2. Info API auth header - Authorization: Bearer <GOLDRUSH_API_KEY>. Same key as Foundational/Streaming/Pipeline.
3. WebSocket API endpoint URL - wss://hypercore.goldrushdata.com/ws?key=<GOLDRUSH_API_KEY>. Auth is a ?key= query parameter at connect time; no Authorization header is sent. Same key as the Info API.
4. Wire-compat with Hyperliquid - Info API request body and WebSocket subscription payloads are byte-for-byte identical to the public Hyperliquid endpoints for implemented types/channels.
5. l4Book is GoldRush-only - it does not exist on wss://api.hyperliquid.xyz/ws. coin is required; l2Book’s coin is optional (wildcard streams every asset).
6. HIP-3 and HIP-4 syntax - <deployer>:<symbol>-<quote> for OHLCV pairs (e.g. xyz:GOLD-USDC); plain symbol for OHLCV tokens.
7. Streaming chain enum - HYPERCORE_MAINNET (SCREAMING_SNAKE_CASE), not hypercore-mainnet.
8. Historical depth - HyperCore data starts at block 606,858,021 (2025-05-25T14:32:53Z); HyperEVM goes back to genesis.
9. No rate limits on the Info API, WebSocket API, or Streaming API for HyperCore. No 1000-subscription-per-IP cap on the WebSocket API.
