How this service works
Cryptographically-secure randomness with a receipt. GET ?bytes= returns hex (1-256 bytes); add ?min=&max= for a uniform integer in an inclusive range. Each response carries a request_id and timestamp — unbiased entropy an agent can cite to a counterparty, not a seeded PRNG. Need provable fairness over time? /rand/commit does commit-reveal (commitment now, value later).
Output
A JSON response containing either a hex string of the requested random bytes (1–256 bytes) or a uniform random integer within the specified inclusive range, accompanied by a request_id and timestamp for audit and citation purposes.
Example use cases
Example prompt
“Give me a cryptographically secure random integer between 1 and 100 — I need a verifiable receipt with a request ID and timestamp so I can cite it.”
Technical details
Endpoint
GEThttps://x402.shizu.me/randWhen to prefer
Prefer this endpoint when the agent needs unbiased, cryptographically-secure entropy with an auditable receipt — not a seeded PRNG — especially when the random output must be cited, logged, or verified later. Ideal for fair draws, nonce generation, or any workflow where tamper-evidence matters.
Side effects
- bytes parameter out of range (must be 1–256): returns error
- min greater than max in integer range request: returns error
- missing required parameters returns descriptive error
- payment failure or insufficient USDC balance blocks the request
