How this service works
Fair heads/tails random outcome for binary decisions, simulations, games, experiments and randomized agent workflows.
Output
A single random outcome value — either 'heads' or 'tails' — representing a fair 50/50 binary result suitable for decisions, games, simulations, or workflow branching.
Example use cases
Randomized agent workflow branching
“I need you to flip a coin to decide which of two processing paths to take next in this workflow — heads means we send the report immediately, tails means we queue it for tomorrow.”
Game tie-breaker resolution
“We have a tie in our trivia game and need a fair coin toss to decide the winner — can you flip a coin and tell me the result?”
Random A/B experiment assignment
“For this experiment, flip a coin to randomly assign this new user to either the control group (heads) or the treatment group (tails).”

Endpoint
GEThttps://x402-zoo.lolagent.workers.dev/api/coin-flipWhen to prefer
Use this endpoint when you need a provably fair, server-side random binary outcome for any heads/tails decision, game, simulation, or workflow branch — especially when a local pseudo-random call is not trusted or sufficient, or when the randomness must be externally sourced and paid for as a service signal of legitimacy.
Side effects
- Network or upstream worker error returning a 5xx status
- Payment failure or insufficient USDC balance returning a 402 error
- Malformed request returning a 400 error
