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 single random integer within the specified min/max range, generated deterministically from the combination of server seed (pre-committed via SHA256 hash), client seed, nonce, and round identifier — allowing anyone to later verify fairness by checking the revealed server seed against the published commit.
Example use cases
Lottery ticket number draw
“Pick a provably-fair random number between 1 and 1000 using client seed 'lottery2024', nonce 5, for round 7 — I need something I can verify later.”
On-chain game dice roll
“Roll a fair random number between 1 and 6 for round 12 of my game, using client seed 'player_abc' and nonce 3 so the outcome is auditable.”
Raffle winner selection
“Generate a provably-fair integer between 1 and 500 for round 1 of my raffle, with client seed 'raffle_event' and nonce 1, so participants can verify the result.”
Technical details
Endpoint
GEThttps://pyfile-agent.taile3ff35.ts.net/data/fair/drawWhen to prefer
Choose this endpoint when you need a single random integer with cryptographic provable fairness — i.e., the result can be verified post-draw by anyone who knows the server seed, client seed, and nonce. Ideal for games, lotteries, raffles, or any scenario requiring an auditable random draw. Prefer this over /fair/pick when selecting a number rather than a winner from a list, and over /fair/verify when you want to generate (not re-verify) a draw.
Side effects
- Missing required query parameters (client_seed, nonce, min, max, round) result in an error response
- min greater than or equal to max returns an invalid range error
- Invalid nonce or round ID format may cause a 400 error
- Payment failure (x402) if USDC is not provided or insufficient
- Round not yet committed may return an error if commit step was skipped
