# Dice Notation Parser

> Dice Notation Parser is a paid API for AI agents from x402-zoo.lolagent.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Parses and validates tabletop RPG dice notation expressions (e.g. d20, 2d6, 3d8+2) without rolling them, returning structured components.

## 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 dice-notation-parser-2d219372
```

Example prompt: Can you parse the dice notation '3d8+2' and tell me what the number of dice, die type, and modifier are?

## When to prefer this

Choose this endpoint when you need to parse and validate dice notation strings without actually simulating a roll — ideal for input validation, display formatting, probability setup, or teaching users what a dice expression means. Prefer this over a full dice roller when you only need the structure, not a random result.

## Known failure modes

- Malformed or unrecognized notation string returns a validation error
- Missing 'notation' query parameter causes a 400 bad request
- Non-standard extensions beyond XdY+Z format may not be supported
- Empty string input likely returns invalid/error response

## How this service works

Parse and validate tabletop dice expressions such as d20, 2d6 and 3d8+2 without rolling.

## Output

A structured breakdown of the dice notation expression, including the number of dice, the number of faces on each die, and any numeric modifier (e.g. +2 or -1), along with a validity flag indicating whether the notation is well-formed.
