Quartermaster Random Pick x402 REST usage

Pick one or several options at random from a caller-supplied list (CSPRNG), optionally without replacement — a decision-maker for agents.

Quartermaster Random Numbers x402 REST usage

Cryptographically-secure random integers in a chosen range (CSPRNG, rejection-sampled to avoid modulo bias) — real entropy an LLM cannot produce itself.

Verifiable Randomness x402 REST usage

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 a...
