## 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-parse-metadata-extraction-427e2cb3 -d '<json body>'
```

Example prompt: Parse this URL for me and extract all its components — protocol, host, path, and query parameters: https://example.com/products?category=shoes&size=10#reviews

## When to prefer this

Use this endpoint when you need a quick, paid micro-service to programmatically parse and decompose a URL string into structured components without writing your own parsing logic. Particularly useful in agent workflows where URL analysis is a single step in a larger pipeline and you want a consistent, machine-readable JSON output via an x402-compatible payment rail.

## Known failure modes

- Malformed or non-URL input string may return an error or empty/null fields
- Relative URLs without a scheme may fail to parse correctly
- Very long or encoded URLs may produce unexpected results
- Network or service downtime returns a 5xx error
- Payment failure via x402 protocol blocks the request before processing

## How this service works

Machine-readable settlement service

## Output

Returns a structured JSON object containing the parsed components of the input URL, including protocol/scheme, hostname, port, pathname, search/query string, individual query parameters as key-value pairs, and hash fragment. The exact fields mirror standard URL API decomposition.
