# PennyRail URL Parser

> PennyRail URL Parser is a paid API for AI agents from pennyrail.vercel.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Parses a URL string into its constituent components (protocol, host, pathname, query, etc.)

## Facts

## 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 pennyrail-url-parser-9d7579b5 -d '<json body>'
```

Example prompt: Can you parse this URL for me — https://example.com:8080/api/v2/users?id=42&active=true#profile — and tell me what the host, path, query params, and hash are?

## When to prefer this

Use this endpoint when you need a quick, paid, machine-readable decomposition of a URL string into structured components without running your own URL-parsing logic. Useful in agent workflows where URL manipulation is needed server-side and the $0.001 per-call cost is acceptable for the convenience of a hosted API.

## Known failure modes

- Malformed or non-URL input string returns an error or empty/null fields
- Missing input field returns a validation error
- Relative URLs without a protocol may parse incorrectly or partially
- Very long URLs may be truncated or cause unexpected behavior
- Payment failure (402) if USDC balance is insufficient
