Entropy for Institutions
For sovereign cryptographic infrastructure, regulated industries, and organisations operating at scale.
Custom Deployment Fleets
Dedicated EC2 or hybrid clusters, isolated per institution, optimised for entropy generation, streaming, and storage with private VPC architecture and automated scaling.
Terabit-Scale Throughput
Achieve TB/s-level data flows via direct S3 integration, bypassing HTTP bottlenecks for mass data provisioning with zero request overhead and deterministic delivery.
Custom Endpoint Integration
Integrate SOPH natively within your systems with bespoke API endpoints, white-label SDK support, and seamless integration with existing key management layers.
Security-Throughput Control
Achieve tailored equilibrium between entropy depth and performance with tunable complexity parameters and theoretically infinite security through chained entropy paths.
Geographically Anchored Environments
Region-specific natural landscapes influence entropy evolution, ensuring regional sovereignty and enabling jurisdictional compliance with true geo-physical differentiation.
Immutable Audit Trail
Every operation is cryptographically signed and permanently recorded for full forensic traceability with immutable logs and optional external audit feeds.

Frequently Asked Questions
What is SOPH?
SOPH is a high-performance entropy generation service that provides cryptographically secure random data for applications requiring true randomness. Our service offers both stateless and streaming endpoints for various use cases.
How does the free tier work?
The free tier provides 1 API call per second, 0.01 MB data cap, and access to 4 stateless endpoints. It's perfect for testing, development, and small projects. No credit card required.
What's the difference between stateless and streaming endpoints?
Stateless endpoints return entropy data immediately in a single request-response cycle. Streaming endpoints provide continuous entropy streams over WebSocket connections, ideal for real-time applications requiring ongoing random data.
Can I upgrade or downgrade my plan?
Yes, you can upgrade or downgrade your plan at any time. Changes take effect immediately, and billing is prorated based on your current billing cycle.
What payment methods do you accept?
We accept all major credit cards (Visa, Mastercard, American Express) and PayPal. All payments are processed securely through Stripe.
Is there a discount for annual billing?
Yes! Annual billing saves you 20% compared to monthly billing. Quarterly billing saves you 10%. These discounts are automatically applied when you select the respective billing periods.
How secure is the entropy data?
All entropy data is generated using cryptographically secure methods and has passed all major battery tests recommended by international standards. We use 256-bit security for all tiers, with enhanced security features available in higher tiers.
What happens if I exceed my plan limits?
If you exceed your plan limits, your requests will be rate-limited or temporarily suspended. You can purchase add-ons to increase your limits or upgrade to a higher tier plan.
Do you offer enterprise support?
Yes, we offer dedicated enterprise support for Scale tier customers and above. This includes priority support, custom integrations, and dedicated account management.
Can I cancel my subscription anytime?
Yes, you can cancel your subscription at any time from your account dashboard. Your service will remain active until the end of your current billing period.
