## 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-classes-as-csv-493d6c0a
```

Example prompt: Can you pull all the CSS classes from https://example.com and give me a CSV with the class names and how many times each one appears on the page?

## When to prefer this

Choose this endpoint when you need a structured, machine-readable CSV of all CSS classes present on a specific web page, especially for front-end audits, design-system analysis, or feeding class data into automated pipelines. It requires no browser or JavaScript rendering and is optimized for single-page, single-element-type extraction at low cost. Prefer this over JSON or text variants when downstream tooling expects CSV format.

## Known failure modes

- Invalid or unreachable URL returns an error with no CSV output
- Page with no class attributes returns an empty or header-only CSV
- Paywalled or bot-blocked pages may return incomplete or empty results
- Malformed HTML may result in partial class extraction
- Network timeout if the target page is slow to respond

## How this service works

Extract the page's classes as csv: fetches the URL, pulls every classes 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 document where each row represents a unique CSS class name found on the fetched page, accompanied by a count of how many times that class appears. The response is plain structured text suitable for direct ingestion into spreadsheets, data pipelines, or further analysis.
