How this service works
Coin flip - returns result heads or tails from a cryptographically secure random source, with a fairness flag and the entropy source name
Output
A JSON object containing: 'result' (enum: 'heads' or 'tails'), 'fair' (boolean, always true confirming 50/50 uniform distribution), 'source' (string naming the entropy source, e.g. 'Node crypto'), and 'generated_at' (UTC timestamp string or null).
Example use cases
Random tiebreaker between two options
“I can't decide between two options — flip a cryptographically fair coin and tell me heads or tails so I can use that to break the tie.”
Game or contest randomization
“We need a fair coin flip to decide who goes first in our game — give me a provably random heads or tails result right now.”
Automated workflow random branching
“My workflow needs a random binary branch point — flip a secure coin and return heads or tails so I can route to the next step.”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/fun/coinflip?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a provably fair, cryptographically secure random binary (heads/tails) outcome — not a simple pseudo-random result. It is ideal when verifiability and fairness matter (e.g. disputes, games, auditable workflows) and when you want an explicit confirmation that the source is a CSPRNG. Prefer over rolling your own Math.random() when auditability of the entropy source is required.
Side effects
- HTTP 402 Payment Required if x402 payment header is missing or invalid
- Network timeout if the server is unreachable
- Unexpected null for generated_at if server clock is unavailable
- Invalid JSON response on server-side error
