RNG API
Cryptographically secure random number generation. Certified fair. Auditable. Powers all our draws and winner selection.
What It Does
NIST-approved random number generation for provably fair draws.
Cryptographic Security
FIPS 186-4 compliant. Hardware entropy sources. Seeded randomization.
Gambling Commission Certified
Audited and approved for UK lotteries and draws. Full compliance documentation.
Verifiable Results
Cryptographic signatures. Public seed values. Third parties can verify fairness.
Batch Generation
Generate millions of random numbers in seconds. Bulk processing supported.
Configurable Output
Integer, hex, binary, or custom ranges. Weighted distributions supported.
Audit Trails
Immutable logs of all generations. Timestamps and signatures for compliance.
How It Works
Request
Specify range (min/max), quantity, and optional seed value.
Generate
NIST algorithm generates random numbers from hardware entropy.
Sign
Results cryptographically signed. Timestamp and metadata included.
Return
Results returned with signature. Immutable audit record created.

Frequently Asked Questions
What is the RNG API?+
Cryptographically secure random number generator for fair draws. Powers all prize selections, match winner picks, and randomization. Certified by independent auditors. Verifiable by third parties.
Is it truly random?+
Yes. Uses NIST-approved algorithms (FIPS 186-4). Seeded from hardware entropy sources. Independent audited by third parties. Verifiable randomness logs available to participants.
Can results be disputed?+
No. All RNG results are cryptographically signed and logged. Participants can verify draws independently using published seed values and algorithms. Transparent and tamper-proof.
What parameters can I set?+
Minimum/maximum value range • Seed value (optional) • Quantity (batch generation) • Output format (integer, hex, binary) • Timestamp of generation for audit trails
How fast is it?+
Generates 1M+ random numbers/second. Sub-millisecond latency. Designed for high-volume draws with thousands of participants.
Can I use it for other purposes?+
Our API is optimized for fundraising draws. Custom licensing available for other use cases. Contact sales for details.
What about algorithm transparency?+
Full source code of RNG algorithm available for review. White papers published on our approach. Independent audits annual. Participants can request verification documents.
Is there a performance guarantee?+
Yes. 99.99% availability SLA. Designed for peak loads (e.g., thousands of simultaneous draws). Redundant systems across multiple regions.
How do I integrate with it?+
REST API endpoint. Provide parameters, get cryptographically signed result. Webhook notifications for batch operations. SDK available in Python, JavaScript, Go.
