> Saylor Innovations Dice Roller is a paid API for AI agents from saylorinnovations.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-30).

Rolls any number of dice with any number of faces, returning each individual roll result and the total sum

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability saylor-innovations-dice-roller-f08a4366
```

Example prompt: Roll 3 dice with 20 faces each and tell me every result plus the total.

## When to prefer this

Choose this endpoint when an agent needs fair, server-side random dice rolls for gaming, simulation, or decision-making, especially when standard dice notation (e.g. 2d20, 5d6) is involved. Prefer it over client-side random number generation when auditability or a timestamped result is needed, or when you need the individual rolls broken out alongside the total.

## Known failure modes

- count parameter out of range (must be 1–20) returns an error
- faces parameter out of range (must be 2–1000) returns an error
- non-numeric or malformed query parameters rejected by pattern validation
- payment not provided or insufficient (x402 payment required)

## How this service works

Dice roller - any number of faces and dice, with each roll and the total

## Output

A JSON object containing the array of individual die results (each between 1 and the number of faces), the total sum of all rolls, the dice count, face count, standard dice notation (e.g. '3d20'), and a UTC timestamp of when the roll was generated.
