random_int
Random integer
Return a uniformly distributed random integer in [min, max], derived from a signature-verified drand quicknet beacon mixed with a server secret and, when a public KiwiSDR receiver delivers one, a hash of live HF atmospheric noise. The response carries the drand round, the beacon signature, a per-request nonce, a commitment hash binding them to the value, a URL where the round can be re-verified, and a `physical` block stating whether noise went in and from where. Free and rate-limited.

random_int_signed
Random integer (paid)
Return a uniformly distributed random integer in [min, max] with the same drand quicknet provenance as random_int, plus a payment receipt. Costs $0.01 per call in stablecoin over the Machine Payments Protocol. New unpaid challenge requests are safety-limited. An unpaid call answers with a payment challenge (JSON-RPC -32042); a client that cannot pay should use random_int instead.

status
Service status
Report service and beacon health: the current drand quicknet round, which relay answered, the rate-limiter mode, and whether the last draw obtained live atmospheric noise. Free, and does not consume rate limit.
