Quantum-Seeded
Randomness.
One API call.

Quantum entropy over a simple REST API — hex, bits and integers. Served from a NIST DRBG seeded with real IBM Quantum hardware measurements and reseeded daily, with simulator or direct hardware runs on request and an OS CSPRNG fallback — and every response is labelled with the source that produced it.

Nine Qntyx products
draw from QuantumRand.

These Qntyx products request randomness from this API for keys, nonces and seals. If QuantumRand is unreachable they fall back to the operating system's random generator, so not every value they produce is quantum-seeded. Qntyx's other products (DB Shield, Endpoint Shield, Mail Seal, Messenger, Threat Feed, Zero Trust) use the operating system's generator directly.
