Random Sample

by Solgiery Random in Onchain & crypto

x402 APIPassing, checked 3 h ago

Select count items as an ordered sample. replace defaults to false: each original index may occur once and count must not exceed the input length. With replace=true, draws are independent and indices may repeat. Uses the server OS CSPRNG. Returns consumed bytes for reproducible calculation, not proof of their origin. Price: 0.007 USDC per request, including the bounded batch.
