Streaming Infrastructure

REAL-TIME
STREAMING API

Our protocol is optimized for speed. Subscribe to listings and delistings via bidirectional streams with zero-buffer delivery.

wss://stream.listingapis.com/v1

Low-latency persistent connection for sub-millisecond event delivery. Ideal for browser-based terminals and lightweight bots.

Example Protocol

// Subscribe to events
{
  "action": "subscribe",
  "channels": ["listings", "delistings"],
  "symbols": ["ALL"] // or ["BTC", "ETH"]
}

grpc.listingapis.com:443

High-performance bidirectional streaming via HTTP/2 and Protobuf. Recommended for institutional-grade infrastructure.

    returns (stream MarketEvent);
}
