What is Light Rider EMS? ​

Light Rider EMS is a cloud service for cryptographic-grade entropy from independent quantum and classical sources. Every response includes the random bytes and a signed receipt.

Cloud endpoint: https://ems.lightriderinc.com

What it provides ​

  • Policy-based access to quantum-verified, high-quality, and low-latency entropy.
  • Health testing and conditioning before entropy reaches a serving pool.
  • Signed receipts that record source, quality, extractor, and health metadata.
  • Multi-source extraction for applications that need independent contributors.
  • REST and WebSocket APIs through one cloud endpoint.

How a request works ​

  1. Collectors read enabled entropy sources.
  2. Health and quality checks reject failing input.
  3. Extractors condition accepted input.
  4. Conditioned entropy enters a policy pool.
  5. EMS serves the requested bytes and signs a receipt.

EMS fails closed. It does not silently replace a required quality tier with weaker entropy.

Use the official SDK ​

The official Python package is lightrider. EMS classes are available from the package root and lightrider.entropy.

python
from lightrider import EntropyClient, Policy

with EntropyClient("https://ems.lightriderinc.com", api_key="lr_...") as client:
    client.fetch_verifier()
    response = client.get_bytes(32, policy=Policy.QUANTUM_VERIFIED)
    print(response.bytes_.hex())
