unprobed
Cryptographically secure random picker for 2-100 JSON choices. Use for low-stakes one-off random or weighted selection, unbiased tie-breaking, and sampling. Returns the selected value and index, request ID, and weight totals for audit logs. $0.001 USDC per paid request. Not for stable assignments, gambling, security tokens, or consequential decisions; outcomes are not provably fair.
Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
