Frequently Asked Questions
How is usage measured?
Usage is measured by total bytes of entropy delivered, not by number of API calls. The Free tier covers 10 MB of entropy per month, Pro covers 1 GB per month. Bulk download endpoints count their full transfer size. See documentation for per-call size limits.
Where does the entropy actually come from?
From photonic shot noise captured by an isolated high-resolution NoIR CMOS sensor at our hardware node. The raw signal is conditioned through LSB extraction, Von Neumann debiasing, and SHA3-256 hashing per NIST FIPS 202. Validation results are published on our /stats page and in our NIST certificate.
Do you keep a copy of the random numbers I receive?
No. Conditioned entropy is delivered to your API call and discarded from memory. We log standard request metadata (timestamp, API key, byte count) for billing and rate limiting only.
What's the typical API latency?
30–80 ms end-to-end depending on geographic location. For latency-sensitive workloads, the SDK supports pre-fetched entropy buffers that eliminate round-trip latency on each random() call.
What happens if I exceed my monthly quota?
Requests return HTTP 429 (Too Many Requests) until the next billing cycle. You can upgrade tiers at any time in your dashboard.
How does Quey compare to random.org or ID Quantique?
random.org sources atmospheric noise and is excellent for general-purpose use, but doesn't publish raw statistical reports per batch and isn't designed for high-volume programmatic SaaS access. ID Quantique sells certified hardware appliances ($25k+) for regulated industries — different market entirely. Quey sits between them: a hardware-backed entropy API for developers and researchers who need physical randomness without buying or operating hardware.
Is Quey suitable for cryptographic key generation?
Quey provides statistically validated entropy suitable as input to cryptographic key derivation functions. For high-stakes regulated production cryptography (banking, defense), regulators may require certified hardware (FIPS 140-2/3, Common Criteria); Quey is not currently certified to those standards. We recommend Quey as a complement to or replacement for OS PRNGs in non-regulated contexts, and for seeding cryptographic operations where verifiable physical entropy is valuable.
What SDKs are available?
Python (pip install quey-random) and Node.js (npm install quey-random) are officially supported. Direct REST integration works from any language. Go and Rust SDKs are on the roadmap.
Can I see the entropy being generated?
Yes — visit our /stats page for a live feed of sensor output and statistical health metrics.
Is the SDK open source?
Yes — github.com/QueyQuantum.
