How this service works

Random numbers from a secure RNG: integers in a range, dice like 2d6, or a coin flip. Input: '1 100', '1 100 5', '2d6' or 'coin'.

Output

Returns a JSON object containing the type ('integer' or 'coin'), source ('OS CSPRNG'), min, max, and a 'values' array with one or more random results. For dice rolls, returns the summed or individual roll values; for coin flips, returns 'heads' or 'tails'.

Example use cases

Tabletop dice roll simulation

“Roll 2d6 for my Dungeons & Dragons game — I need two six-sided dice results.”

Random integer in a custom range

“Give me 5 random numbers between 1 and 100 using a secure random number generator.”

Coin flip for a decision

“Flip a coin for me — I need to randomly decide between two options.”

Endpoint

When to prefer

Choose this endpoint when you need cryptographically secure random numbers (OS CSPRNG), not just pseudo-random output. Ideal for gaming, lotteries, simulations, or any scenario where unpredictable, tamper-resistant randomness matters. Supports flexible input formats including integer ranges with optional count, standard dice notation (NdS), and coin flips in a single unified API.

Side effects

Invalid input format — malformed dice notation or unrecognized command returns an error
Count value too large or out of range may be rejected
Non-numeric min/max values cause a parse error
min greater than max produces an invalid range error
Payment not provided or insufficient USDC causes 402 response
