Uniform dice rolls in one GET: count dice with sides faces, returned as rolls[], total, notation and the possible range. crypto.getRandomValues with rejection sampling removes modulo bias; nothing is fetched or stored. curl: GET /dice?count=2&sides=6 . Response: {"notation":"2d6","rolls":[4,2],"total":6,...}. count 1..100 (default 1), sides 2..1000 (default 6); a non-integer or out-of-range value is 400 before payment. No seed and no signed beacon; each paid call returns fresh rolls. No keys, no account, one GET, one delivery — 0.001 USDC. A purchase is two calls by design: this first call returns 402 with the price and the payment terms, and you then repeat the same request with the PAYMENT-SIGNATURE header to receive the 200 delivery.
