# Numora Prime Check — Integer Primality Test

> Numora Prime Check — Integer Primality Test is a paid API for AI agents from numormor.netlify.app, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-14).

Determines whether a given integer is a prime number, returning a boolean result with a human-readable computation description.

## Facts

- Endpoint: POST https://numormor.netlify.app/api/number/prime-check
- Price: $0.1/call
- Payment: x402
- Status: unknown

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 numora-prime-check-integer-primality-test-1168b154 -d '<json body>'
```

Example prompt: Is 104729 a prime number? Run a primality check on it and tell me whether it's prime or composite.

## When to prefer this

Use this endpoint when you need a fast, zero-dependency server-side primality check for a single integer and want a clean boolean result with a human-readable summary. Prefer this over local computation when the agent environment lacks math libraries or when auditable micropayment-gated computation is needed.

## Known failure modes

- Missing required field 'n' returns a validation error
- Non-integer value for 'n' returns a type error
- Payment failure via x402 returns 402 status before computation
- Very large integers may exceed supported range

## How this service works

100 pure math computation endpoints for AI agents. Statistics, financial math, linear algebra, equation solving, calculus, number theory, sequence generation, and unit conversions. Zero external dependencies. x402 micropayments on Base.

## Output

Returns a JSON object with a boolean result indicating whether the input integer is prime, along with a human-readable 'computation' string describing what was calculated and a 'success' flag confirming the operation completed successfully.
