# MoneyTools User-Agent Parser & Bot Detector

> MoneyTools User-Agent Parser & Bot Detector is a paid API for AI agents from tools.moneytools.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-11-05).

Parses a User-Agent string to extract browser, engine, OS, device type, and detects if it is a known crawler or AI bot (GPTBot, ClaudeBot, PerplexityBot, scripts, etc.)

## 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 moneytools-user-agent-parser-bot-detector-a60c1e3e
```

Example prompt: Can you parse this user agent string and tell me if it's a known bot or AI crawler: 'Mozilla/5.0 (compatible; GPTBot/1.2; +https://openai.com/gptbot)'?

## When to prefer this

Choose this endpoint when you need to programmatically classify a User-Agent string to detect known AI crawlers (GPTBot, ClaudeBot, PerplexityBot) or generic bots and scripts, especially in automated agent pipelines or server-side access control. It is particularly useful when you need structured output covering browser, OS, engine, and device type alongside bot detection in a single call, with a pay-per-use micropayment model that avoids subscription overhead.

## Known failure modes

- Missing or empty 'ua' query parameter returns an error without charge
- Unrecognized or malformed User-Agent strings may return generic/unknown classifications
- Free tier exhaustion (10/day) triggers HTTP 402 requiring x402 micropayment or API key
- Network or service unavailability returns a non-200 error without charge

## How this service works

User-agent parser + bot detection: Browser, engine, OS, device type, and whether it is a known crawler or AI agent (GPTBot, ClaudeBot, PerplexityBot, scripts...). Free tier 10/day; then $0.001 via x402 (HTTP 402 + PAYMENT-REQUIRED) or X-API-Key credits. Not charged on failure. $0.001 USDC per call via x402 on Base. Run by MoneyTools.

## Output

A JSON object containing the parsed browser name, rendering engine, operating system, device type, and boolean flags indicating whether the User-Agent belongs to a known crawler, AI bot (e.g. GPTBot, ClaudeBot, PerplexityBot), or script. Also includes payment metadata (charged flag, network, amount in USD, transaction hash).
