## 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 kihustle-prime-checker-bd879fd3 -d '<json body>'
```

Example prompt: Can you check if 97 is a prime number?

## When to prefer this

Use this endpoint when you need a simple, fast, paid API call to determine if a single integer is prime, particularly in agentic workflows where a micro-payment model (x402, USDC) is acceptable and you want a lightweight external computation rather than running local math.

## Known failure modes

- Missing or non-integer 'number' field returns an error
- Extremely large integers may cause processing failures or timeouts
- Non-numeric input types rejected at schema validation
- Service may return generic 'processed' status without explicit true/false prime verdict

## How this service works

Kostenlose Guides, Solo-Playbooks und Artikel zu KI, Automation und Side Hustles — für Menschen, die mit echten Systemen online Einkommen aufbauen wollen. Transparent finanziert über faire Affiliate-Links.

## Output

Returns a JSON object with a 'result' field (e.g. 'processed') and a 'status' field (e.g. 'success'), indicating whether the computation completed. The actual primality verdict is implied by the result field but the response schema is minimal — agents should treat a 'success' status as confirmation the check ran.
