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 one or more random numbers within the specified range, or a shuffled/picked subset of the provided items, along with the drand beacon round number so any third party can independently re-verify the randomness source.
Example use cases
Giveaway winner selection
“I have 8 entrants in my giveaway: Sarah, Mike, Jordan, Priya, Tom, Lena, Carlos, Yuki — randomly pick 1 winner using a verifiable beacon so I can prove the draw was fair.”
Random number for board game
“Roll me a fair random number between 1 and 20 that I can verify wasn't rigged — like a provable dice roll for our online game.”
Shuffling a playlist or task list
“Shuffle this list of tasks for me in a provably fair order: 'Write report|Review PRs|Update docs|Send invoices|Team standup' — I want to be able to verify the shuffle was random.”
Technical details
Endpoint
GEThttps://agentrxi.com/v1/random?utm_source=zero.xyzWhen to prefer
Choose this endpoint when auditability and provable fairness are important — e.g., public giveaways, lotteries, or game mechanics where participants need to verify the random outcome independently. It is superior to pseudo-random alternatives when you need a beacon round ID to prove the result was not manipulated. Prefer over local RNG when a third-party verifiable source is required.
Side effects
- Missing required 'type' or 'method' fields returns a validation error
- Items string not pipe-separated may result in incorrect parsing
- Count exceeding available items in pick mode may return an error
- drand beacon temporarily unreachable causes a service error
- Invalid min/max range (min >= max) returns a validation error
