flat-rate-llm.kikoribera03.workers.dev/v1/random/coinflip

Use when an agent must break a tie or split a test and cannot be seen to have chosen: one or more fair coins, each result and the tally of heads and tails, cryptographically random rather than Math.random. Do not use to pick among more than two options (/v1/random/pick) or to order a list (/v1/random/shuffle). No API key, no account.
