Streaming entropy

Use the WebSocket endpoint for continuous, receipt-attested entropy.

Endpoint: wss://ems.lightriderinc.com/v1/entropy/stream

Query parameters

• policy: required routing policy.
• bytes_per_tick: 1 to 4,096 bytes, default 64.
• application_id: optional caller identifier.

Each JSON frame contains bytes_hex and receipt. If EMS cannot serve the required quality, it sends an error frame and closes the connection.

const ws = new WebSocket(
  'wss://ems.lightriderinc.com/v1/entropy/stream' +
  '?policy=fastest_available&bytes_per_tick=128'
);

ws.onmessage = (event) => {
  const frame = JSON.parse(event.data);
  if (frame.error) throw new Error(frame.error);
  consume(frame.bytes_hex, frame.receipt);
};

Browser WebSocket connections use the anonymous Free entitlement. Use a WebSocket client that can send an Authorization header for higher tiers.
