How this service works
Verifiable random numbers from the drand public beacon (League of Entropy): numbers in a range, or a fair shuffle and pick of your items, with the beacon round so anyone can re-check the result.
Output
Returns a random number within the requested range (or a shuffled/picked result from the provided item list), along with the drand beacon round number that anyone can use to independently verify the randomness at the League of Entropy's public beacon.
Example use cases
Fair giveaway winner selection
“I have 8 contestants in my Twitter giveaway — Alice, Bob, Carol, Dave, Eve, Frank, Grace, Hank — pick one winner at random using a public randomness beacon so everyone can verify it was fair.”
Random number for tabletop game
“Roll me a random number between 1 and 20 using the drand beacon so my players can verify it wasn't rigged, and give me the beacon round number.”
Shuffle team assignments randomly
“Randomly shuffle these 6 teams for our tournament bracket: TeamA|TeamB|TeamC|TeamD|TeamE|TeamF — I need the result to be publicly verifiable so no one disputes the draw.”
Technical details
Endpoint
GEThttps://agents.citiviewgroup.com/v1/random?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need publicly auditable, cryptographically verifiable randomness — not just pseudo-random output. It is ideal for lotteries, giveaways, games, and any scenario where participants may dispute the fairness of random selection, since the drand beacon round lets anyone independently re-verify the result. Prefer this over standard PRNG endpoints when trust and transparency matter.
Side effects
- drand beacon temporarily unreachable — service returns an error if the public randomness network is unavailable
- invalid parameter types (e.g. non-integer min/max) cause a 400 bad request
- min greater than max results in an invalid range error
- items parameter malformed (not pipe-separated) may return unexpected results
- count exceeding the number of items when picking without replacement may return an error
