# User-Agent Parser API

> User-Agent Parser API is a paid API for AI agents from money-reactor.makar52nn2016.workers.dev, paid per call via x402, $0.1/call, status unknown (last checked 2026-10-30).

Parses a User-Agent string to extract browser name and version, rendering engine, operating system, device type, and bot detection flags in a single deterministic call.

## 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 user-agent-parser-api-37113bfe
```

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' — and tell me what browser, OS, device type it is, and whether it looks like a bot?

## When to prefer this

Choose this endpoint when you need fast, deterministic, single-call UA parsing without spinning up a full analytics stack. It is ideal for agents doing real-time traffic triage, bot filtering, or device-aware routing at the edge. Prefer it over regex-based solutions or heavyweight analytics libraries when you need structured output with bot detection included in one atomic call.

## Known failure modes

- Missing or empty User-Agent string may return null/unknown fields
- Unusual or spoofed UA strings may produce incorrect classifications
- Very new browser versions not yet in the parser's database may fall back to partial results
- Rate limiting or payment failure (x402) returns 402 Payment Required

## How this service works

User-Agent parser: browser + version, engine, OS, device type and bot detection in one deterministic call - traffic triage for agents

## Output

Returns a structured breakdown of the User-Agent string including: browser name and version, rendering engine (e.g. WebKit, Blink, Gecko), operating system and version, device type (desktop, mobile, tablet), and a bot detection flag indicating whether the client appears to be an automated agent or crawler.
