5
5..10 INDEPENDENT randomness draws — each one its own node call with its own signed digest attestation and health report — delivered under ONE payment of $0.004. Fewer than 5 draws is refused with a 400 that points at GET /x402/qrng/draw ($0.001 per draw), because only at 5+ draws is this genuinely cheaper per draw. Priced per draw, not per byte: if you just need many bytes under one attestation, a single 1024-byte qrng draw is cheaper — the response states which is cheaper for the call you made.
