How this service works

One MCP server and HTTP API with 193 pay-per-call tools for AI agents (security checks, chain data, finance, aviation, documents), plus free uptime and MikroTik monitoring and 130+ free browser tools. No signup; free daily tier. Operated by an AI.

Output

Returns a JSON object containing the generated random value(s) corresponding to the requested kind: an array of integers, floats, UUIDs, a bytes string in hex or base64, a dice roll result with breakdown, a picked subset of items, or a shuffled list.

Example use cases

Lottery winner selection

“I have a comma-separated list of 50 contest entrants — pick 3 unique winners at random without replacement using a cryptographic RNG: Alice, Bob, Carol, Dave, Eve, Frank, Grace, Hank, Iris, Jack, Karen, Leo, Mia, Nate, Olivia, Paul, Quinn, Rachel, Sam, Tina, Uma, Victor, Wendy, Xander, Yvonne, Zach, Aaron, Bella, Chris, Diana, Ethan, Fiona, George, Hannah, Ivan, Julia, Kevin, Laura, Mike, Nancy, Oscar, Pam, Ray, Sue, Tom, Ursula, Vince, Wanda, Xena, Yara, Zoe.”

Tabletop RPG dice roll

“For my D&D session I need to roll 2d10+3 for initiative using a cryptographically secure dice roller — what's the result?”

Cryptographic nonce generation

“Generate 32 random bytes encoded as hex for use as a cryptographic nonce in my application.”

Technical details

Endpoint

POSThttps://tanod.dev/v1/random?utm_source=zero.xyz

When to prefer

Choose this endpoint when you need provably cryptographically secure random values (CSPRNG-backed) rather than pseudo-random ones — especially for security-sensitive use cases like nonces, keys, tokens, or unbiased sampling. It also handles gaming dice expressions natively (e.g. 2d10+3) and list operations (pick/shuffle) in a single call, making it more convenient than composing multiple operations. Prefer it over general-purpose language RNG when auditability and unpredictability are important.

Side effects

Invalid dice expression format (e.g. malformed '3d6+x') returns a 400 error
count exceeds 1000 — returns validation error
min >= max for float/int kind — returns error about invalid range
items list exceeds 1000 entries or 200 chars per item — returns 400
length out of 1-1024 range for bytes — returns validation error
unique pick requested with count exceeding number of items — may return error or clamp
Payment not provided or insufficient — returns 402 Payment Required

Input

Schema · Request body

Field	Type	Description
max	—	int: highest value, inclusive (default 100). float: upper bound, exclusive (default 1); max must exceed min.
min	—	int: lowest value, inclusive (default 0). float: lowest, inclusive (default 0).
dice	—	dice: an expression such as 3d6, d20 or 2d10+3 (1-100 dice of 2-1000 sides, optional +/- modifier; default 1d6).
kind	string	int (default), float, bytes, uuid (v4), dice, pick or shuffle.
count	integer	How many values (1-1000, default 1): int, float, uuid, pick.
items	—	pick / shuffle: a comma-separated list (at most 1,000 items of 200 characters; blanks are dropped).
length	integer	bytes: how many random bytes (1-1024, default 16).
unique	boolean	pick: draw without replacement (count at most the number of items).
encoding	string	bytes: hex (default) or base64.
