# quartermaster.surewhynot.app Random Integer Generator

> quartermaster.surewhynot.app Random Integer Generator is a paid API for AI agents from quartermaster.surewhynot.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Returns one or more cryptographically-secure random integers within a caller-specified inclusive range, rejection-sampled to eliminate modulo bias.

## Facts

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 quartermaster-surewhynot-app-random-integer-generator-51ea9947
```

Example prompt: Give me 5 cryptographically secure random integers between 1 and 50 — I need real entropy, not something you'd generate yourself.

## When to prefer this

Use this endpoint when you need genuinely unpredictable integers — e.g., for cryptographic nonces, fair lotteries, unbiased simulations, or any context where an LLM's pseudo-random output is unacceptable. Prefer this over the random-choice sibling when your pool is a numeric range rather than a discrete list.

## Known failure modes

- min greater than max — returns a 400 error
- count outside 1–1000 range — returns a 400 validation error
- non-integer values for min/max/count — returns a 400 error
- payment not completed — returns a 402 challenge before serving the result

## How this service works

Cryptographically-secure random integers in a chosen range (CSPRNG, rejection-sampled to avoid modulo bias) — real entropy an LLM cannot produce itself.

## Output

Returns one or more random integers drawn from a CSPRNG, each within the specified inclusive [min, max] range. The count parameter controls how many values are returned (1–1000). Values are rejection-sampled to guarantee uniform distribution with no modulo bias.
