How this service works
Machine-readable settlement service
Output
Returns a JSON object containing a cryptographically secure random value or set of values, suitable for use in nonces, tokens, seeds, or other security-sensitive contexts.
Example use cases
Secure nonce for API authentication
“I need a cryptographically secure random nonce to include in my next API request signature — can you generate one using PennyRail's secure random utility?”
Random seed for a simulation
“Generate a secure random seed value I can use to initialize a Monte Carlo simulation run — I want it to be cryptographically unpredictable.”
Random token for a raffle
“I'm running a fair digital raffle and need a verifiably random number to pick the winner — use the PennyRail secure random generator to get one I can trust.”
Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/p/nano/utility.random-secure--random?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a cryptographically secure random value in an agent workflow that already handles x402 micro-payment settlement, and you want a simple, paid, tamper-resistant randomness source without running your own crypto library.
Side effects
- Payment failure or insufficient USDC balance causing a 402 response
- Malformed input object causing a 400 validation error
- Service unavailability on the Vercel deployment causing 503 or timeout
- Empty or null input object rejected by schema validation
