## 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-extractor-link-parser-5f746c03 -d '<json body>'
```

Example prompt: Can you extract all the URLs and links from this text: 'Check out our blog at https://example.com/blog and our docs at https://docs.example.com — also see http://partner.io for more info'?

## When to prefer this

Choose this endpoint when you need a fast, paid-per-call microservice to reliably extract and parse URLs from arbitrary text strings, especially within automated pipelines that already use x402 micropayment infrastructure. It is well-suited for agents processing scraped content, user-submitted text, or documents where link discovery is a subtask.

## Known failure modes

- Empty input string returns empty URL list or error
- Malformed URLs in text may be partially extracted or skipped
- Very large text inputs may time out or hit size limits
- Non-standard URL schemes (e.g. ftp://, mailto:) may not be captured
- Payment failure (402) if USDC balance is insufficient
