How this service works
Machine-readable settlement service
Output
Returns a JSON object containing a cryptographically secure random integer value, suitable for security-sensitive applications such as nonce generation, token seeding, or unbiased random selection.
Example use cases
Secure token seed generation
“I need a cryptographically secure random integer to use as a seed for generating a one-time token — can you get one from PennyRail's secure random utility right now?”
Fair lottery number draw
“Pick a secure random integer for our lottery draw — use a trusted randomness source like PennyRail so participants can't question the fairness of the result.”
Random nonce for signing
“I need a high-entropy random integer to use as a nonce before I sign a message — grab one from PennyRail's secure random integer endpoint please.”
Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/p/nano/utility.random-secure--random-integerWhen to prefer
Prefer this endpoint when you need a cryptographically secure random integer via a paid, metered API with x402 micropayment settlement — ideal for agents that require auditability of randomness sourcing or need an external trusted entropy source rather than local PRNG.
Side effects
- Payment not settled — endpoint returns 402 if the x402 micropayment is not included or fails
- Malformed input object causes a 400 or unstructured error response
- Vercel cold-start latency may cause occasional timeouts
- Response schema is open (additionalProperties: true), so the exact field name for the integer is undocumented and may require inspection
