## 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 link-rel-license-44ace6b7
```

Example prompt: Can you check what license links are declared in the HTML of https://example.com — specifically any rel='license' link or anchor tags, resolved to full URLs?

## When to prefer this

Use this endpoint when you need to programmatically discover license declarations embedded in a webpage's HTML link relationships, particularly for auditing content rights, verifying open-source or Creative Commons licensing, or building link-relationship maps. It is purpose-built for rel='license' specifically, making it more precise than a general link extractor when licensing metadata is the focus.

## Known failure modes

- Page returns non-200 HTTP status — no links returned
- Target URL is unreachable or times out
- Page contains no rel='license' links — returns empty list with count of 0
- Page blocks scrapers with bot-detection, resulting in no data
- Malformed relative URLs on the page may cause resolution failures

## How this service works

The rel="license" links of a page: every matching <link>/<a> with href, resolved to absolute URLs, with a count. Link-relationship discovery. $0.01 per page.

## Output

A list of all <link> and <a> elements with rel='license' found on the page, each with its href resolved to an absolute URL, plus a total count of matching links found.
