## 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 extract-stylesheets-as-csv-c655d9e4
```

Example prompt: Can you extract all the stylesheets from https://example.com and give me the results as a CSV with a count of how many there are?

## When to prefer this

Choose this endpoint when you need a lightweight, structured CSV extraction of stylesheet references from a single web page without spinning up a browser. Ideal for agent pipelines and data workflows that need CSS asset inventories in a machine-readable format at very low cost ($0.01/page). Prefer this over full-page scrape APIs when you only need stylesheet elements specifically.

## Known failure modes

- Target URL is unreachable or returns a non-200 status — extraction returns empty or error
- Page uses JavaScript to dynamically inject stylesheets — server-side fetch may miss dynamically loaded CSS
- URL parameter missing or malformed — request fails with validation error
- Page blocks crawlers via robots.txt or WAF — may return empty results or access-denied error
- Page has no stylesheets — returns CSV with count of zero

## How this service works

Extract the page's stylesheets as csv: fetches the URL, pulls every stylesheets element and returns them as CSV rows, with a count. Structured, one-element-type extraction for agents and pipelines; no browser needed. $0.01 per page.

## Output

A CSV-formatted response where each row represents a stylesheet element found on the page (e.g. href, rel, type attributes), plus a total count of stylesheets discovered.
