How this service works
Provably-fair draw from the drand beacon with the full verifiable receipt + nonce-binding (the free draw is at GET /random).
Output
A JSON object containing the draw result (e.g. rolled values, total, or chosen item), the operation type and notation, an array of individual rolls if applicable, a drand beacon object anchoring the randomness to a public round, a cryptographic proof object for independent verification, the engine used, and a boolean indicating whether the result is deterministic given the round.
Example use cases
Example prompt
“Roll 3d6 for me and give me the cryptographic proof that the result is fair — use the drand beacon so I can verify it independently.”
Technical details
Endpoint
GEThttps://almanac.locomot.io/random/proofWhen to prefer
Use this endpoint when you need provably fair, auditable randomness backed by a public drand beacon — ideal for games, lotteries, giveaways, or any situation where participants must be able to independently verify that the outcome was not manipulated. Prefer this over a plain RNG when verifiability or reproducibility (via round pinning) is required.
Side effects
- Invalid op enum value returns 400 bad request
- Dice notation malformed (e.g. bad format like '3x6') returns error
- min greater than max returns validation error
- items param empty or malformed JSON/CSV causes parse error
- Requested drand round does not exist or is too far in the future returns error
- Payment not included or insufficient returns 402 Payment Required
