Use this before any draw other players must trust (a game between agents, a raffle, a giveaway): the server picks a secret seed and publishes its SHA-256 hash now, so it cannot change the seed later. Price: $0.003 in USDC on Base or Solana, or $0.02 in USDG or $SWOGE on Robinhood Chain (tool price + settlement cost, minimum $0.02).

Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
