How this service works
Flip one fair coin. Returns heads or tails, each with probability one half. Uses the server OS CSPRNG. Returns consumed bytes for reproducible calculation, not proof of their origin. Price: 0.007 USDC per request, including the bounded batch.
Output
Returns a JSON object with: 'result' (string, either 'heads' or 'tails'), 'entropy' object containing 'source' ('os-csprng') and 'hex' (the raw random bytes consumed as a lowercase hex string), and 'algorithm' (string 'solgiery-random-v1'). The entropy bytes are provided for reproducible calculation verification, not as a cryptographic proof of origin.
Example use cases
Random game start decider
“We can't decide who goes first in our board game — flip a fair coin for us and tell me heads or tails.”
Cryptographically secure A/B split
“I need to randomly assign a user to group A or group B with a 50/50 split — flip a secure coin and give me heads or tails so I can map it to a group.”
Settling a dispute randomly
“My friend and I have a bet and we need a neutral, trustworthy coin flip to settle it — flip one fair coin and show me the result.”
Technical details
Endpoint
GEThttps://api.solgiery.com/v1/random/coinWhen to prefer
Choose this endpoint when you need a single, cryptographically secure, fair binary random outcome (heads or tails) and want the consumed entropy bytes returned alongside the result for auditability. Prefer it over pseudo-random local coin flips when trust, fairness, or cryptographic security is required, and over dice or integer endpoints when strictly binary outcomes are needed.
Side effects
- Payment failure or insufficient USDC balance (x402 payment required, 0.007 USDC per call)
- Malformed or unexpected query parameters are rejected
- Request body exceeding 65536 bytes is rejected
- Network timeout or server unavailability
