Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

zero fetch --capability x402helper-xyz-link-extractor-a2492636

## When to prefer this

Choose this endpoint when you need a quick, pay-per-use link extraction from a single public URL without standing up your own scraping infrastructure. It is well-suited for lightweight link audits, one-off URL discovery, or agent workflows that need to enumerate links from a page on demand.

## Known failure modes

- URL is not publicly accessible or returns a non-200 status
- URL is malformed or missing the required 'url' query parameter
- Target page has no extractable links
- Target site blocks crawlers or returns a CAPTCHA
- Network timeout or DNS resolution failure
- Payment not completed via x402 protocol results in 402 response
