How this service works
Provably-fair random integer from a committed seed. ?client_seed=s&nonce=1&min=1&max=100&round=1
Output
Returns a random integer within the requested min–max range, derived from a combination of the committed server seed (pre-published as a SHA-256 hash via the /fair/commit endpoint) and the caller's client seed and nonce. The result is deterministic given those inputs, allowing anyone to reproduce and verify it after the server seed is revealed.
Example use cases
Fair lottery winner selection
“Pick a provably-fair random number between 1 and 200 for round 5 of my lottery, using client seed 'lotto2024' and nonce 1, so participants can verify it was fair.”
Verifiable game dice roll
“Roll a fair die for game round 99 — give me a random integer between 1 and 6 using my client seed 'player_alice' and nonce 3 so I can prove it to my opponent.”
Auditable random card draw
“Draw a provably-fair random integer between 1 and 52 for round 10, with client seed 'deck_shuffle' and nonce 2, so I can map it to a playing card and let anyone verify the draw.”
Technical details
Endpoint
GEThttps://pyfile-agent.taile3ff35.ts.net:10000/data/fair/drawWhen to prefer
Choose this endpoint when you need a random integer that is cryptographically verifiable and provably fair — i.e., the server cannot retroactively manipulate the result. Ideal for lotteries, games, raffles, or any scenario where participants must be able to audit the randomness after the fact. Pair with the /fair/commit endpoint to obtain the server seed commitment before the draw.
Side effects
- Missing required query parameters (client_seed, nonce, min, max, round) return an error or unexpected result
- Invalid round ID that has no prior commit may return an error or unverifiable result
- min greater than max causes an invalid range error
- Non-integer values for min, max, or nonce may be rejected
- Network or server errors return HTTP 5xx
