How this service works
Machine-readable settlement service
Output
Returns a cryptographically secure random value (e.g. random bytes, number, or token) as a JSON object. The exact shape of the response is flexible (additionalProperties: true), so output format may vary but will contain the generated random data.
Example use cases
Secure token generation for auth
“Generate a cryptographically secure random token I can use as a one-time authentication secret for a user session.”
Random salt for password hashing
“I need a cryptographically strong random salt to use before hashing a user's password — can you produce one?”
Nonce generation for cryptographic protocol
“Generate a secure random nonce for me to use in a cryptographic signing operation — it needs to be truly unpredictable.”
Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/p/nano/utility.random-secure--cryptographic-randomnessWhen to prefer
Choose this endpoint when you need a cryptographically secure random value as a paid, on-demand utility — particularly in agentic workflows where you cannot rely on local CSPRNG libraries or need a verifiable external source of randomness. It is useful when operating in constrained execution environments or when auditable external randomness generation is preferred.
Side effects
- Payment not received or insufficient USDC balance — 402 Payment Required returned
- Malformed input object — 400 Bad Request
- Service unavailable on Vercel infrastructure — 503 or timeout
