# Sindri True Random Number Generator

> Sindri True Random Number Generator is a paid API for AI agents from x402.outpimp.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Generates a true random number in a specified format (int, float, binary, octal, hex, bigInt, or romanNumeral) within optional bounds

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 sindri-true-random-number-generator-41d0b2f6 -d '<json body>'
```

Example prompt: Generate a random integer between 1 and 1000 — make it a multiple of 10.

## When to prefer this

Use this endpoint when you need a true random number in a specific numeric format (especially non-standard ones like hex, binary, octal, bigInt, or Roman numerals) with optional range or step constraints. Prefer this over pseudo-random client-side generation when format flexibility or trustworthiness of randomness matters. Good for simulations, games, test data generation, and educational tools.

## Known failure modes

- Invalid 'field' enum value returns an error
- min or max values exceeding ±1e15 are capped silently
- fractionDigits outside 0–20 is capped to valid range
- Missing required 'field' parameter may return a validation error
- romanNumeral format may not support negative or zero values

## How this service works

True-random-number generator API. Generates a bounded random number via one of: int, float, binary, octal, hex, bigInt (returned as a string), romanNumeral. Accepts optional locale (default en_US). Numeric args (min, max, multipleOf) are capped to +/-1e15; fractionDigits is capped to 0-20.

## Output

A randomly generated number in the requested format (int, float, binary, octal, hex, bigInt as string, or romanNumeral), bounded by any min/max/multipleOf constraints provided, returned as a JSON response.
