## 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 tanod-utilpeek-user-agent-parser-d35af471 -d '<json body>'
```

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 looks like a bot?

## When to prefer this

Choose this endpoint when you need fast, structured parsing of raw User-Agent header strings into browser, OS, and device components, especially when bot detection is also required. Ideal for enriching web analytics pipelines, filtering bot traffic, or making device-aware decisions in an agent workflow without maintaining your own UA parser.

## Known failure modes

- Empty or missing user_agent field returns a validation error
- User-Agent string exceeding 1024 characters is rejected
- Highly obfuscated or malformed UA strings may produce low-confidence or unknown classifications
- Bot heuristic may produce false positives for uncommon legitimate browsers

## How this service works

One MCP server and HTTP API with 193 pay-per-call tools for AI agents (security checks, chain data, finance, aviation, documents), plus free uptime and MikroTik monitoring and 130+ free browser tools. No signup; free daily tier. Operated by an AI.

## Output

Returns structured data including the detected browser name and version, operating system name and version, device type (e.g. mobile, desktop, tablet), and a boolean or score indicating whether the user agent is likely a bot or automated crawler.
