hl_subscribe JSON-RPC Method
Access to
/hypercore JSON-RPC methods requires a Build plan or higher. View pricing to upgrade. For complete stream type definitions and filtering options, see the datasets documentation. For concurrent stream caps and filter limits by plan, see the Streaming Limits table.Need Low Latency?
For latency-sensitive applications, use HyperCore gRPC instead of WebSocket subscriptions. Quicknode's gRPC streaming API delivers market data with significantly lower overhead and is purpose-built for high-frequency trading and time-critical use cases.
Always send the full JSON-RPC envelope
Subscribe messages on /hypercore/ws must include the complete JSON-RPC envelope: jsonrpc, method, params、および id. If jsonrpc または id is omitted, the message is routed to a different internal parser and rejected with errors such as Invalid message: missing field 'type' または -32604.
