# Numora Prime Check

> Numora Prime Check is a paid API for AI agents from numomo.vercel.app, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-15).

Determines whether a given integer is a prime number

## Facts

- Endpoint: POST https://numomo.vercel.app/api/number/prime-check
- Price: $0.1/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/numora-prime-check-ebc0db2a
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_7FiooVUbVLYm5Z4kN6km6

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-ebc0db2a -d '<json body>'
```

Example prompt: Is 1000003 a prime number? Run a primality check on it.

## When to prefer this

Choose this endpoint when you need a quick, self-contained primality test with no external dependencies. Ideal for AI agents needing deterministic math results without setting up a local math library, and when micropayment-based access via x402 on Base is acceptable. Best for single integer queries rather than bulk primality testing.

## Known failure modes

- Missing required field 'n' returns a validation error
- Non-integer or float input fails schema validation
- Extremely large integers may cause timeout or overflow
- Payment failure (x402) blocks the request before computation

## 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 success flag, a result object indicating whether the input integer is prime, and a human-readable computation description string explaining what was computed.
