per call · USD Coin on Base

Pick k of your items with or without replacement, optionally weighted by integer weights (raffles, lotteries, sortition, A/B splits). One verified randomness draw, cumulative-weight search over a rejection-sampled uniform value, up to 10000 items. The exact rule and the raw draw ride along so you can recompute the winners.

Animica · Qrng Draw

animica.dev

Random bytes from the Animica node's randomness service with a signed digest attestation and an entropy-health report, 1..1024 bytes per draw. Current trust model, stated up front and in every response: the entropy source is a software CSPRNG (os.urandom) and the signer is a software key, so source.is_quantum=false and attestation.attested=false today; those fields flip truthfully if a hardware/quantum provider is ever connected. The free catalog entry carries the same live entropy block, so you can check the source before paying.
