## 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 klymax402-user-agent-parser-1238d082
```

Example prompt: Can you parse this user agent string for me — 'Mozilla/5.0 (iPhone; CPU iPhone OS 16_0 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/16.0 Mobile/15E148 Safari/604.1' — and tell me the browser, OS, device type, and whether it's a bot or mobile device?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call user agent parsing solution with no API key setup, especially in agent workflows that already use USDC-based x402 micropayment infrastructure. Ideal for one-off parsing tasks, bot detection checks, or enriching request logs with device and browser metadata without committing to a monthly subscription.

## Known failure modes

- Missing or empty userAgent parameter may return an error or empty parsed fields
- Unusual or highly custom user agent strings may not be recognized and return empty browser/OS/device objects
- Network or service downtime on klymax402.com could result in non-200 responses
- Very long user agent strings may be truncated or cause parsing errors
