# Agent Micro Prime Checker

> Agent Micro Prime Checker is a paid API for AI agents from agent-micro.annushka1190.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Checks whether a given integer is a prime number, returning a boolean result via a cheap per-call micro-payment endpoint.

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 agent-micro-prime-checker-6757626b
```

Example prompt: Can you check whether 104729 is a prime number using a math micro-tool?

## When to prefer this

Choose this endpoint when you need a quick, cheap, on-demand primality check for a single integer without spinning up your own math library or compute environment. At $0.001 per call paid in USDC via x402, it is ideal for AI agents that occasionally need mathematical validation without maintaining local dependencies.

## Known failure modes

- Missing or invalid 'input' query parameter returns an error
- Non-integer or non-numeric input may return a 400 error
- Payment failure or missing x402 USDC header results in 402 Payment Required
- Very large integers may cause timeout or overflow errors
- Network issues with the Cloudflare Worker may return 5xx errors

## How this service works

Advanced micro-tools for AI agents: cryptographic randomness, text analysis, math helpers, date arithmetic, web metadata, and IP intelligence. All under $0.01 per request, paid in USDC via x402.

## Output

Returns a JSON object with an 'ok' boolean field indicating whether the request succeeded, and likely a result field indicating whether the provided integer is prime.
