## 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-main-as-json-400b79af
```

Example prompt: Fetch https://example.com/article and extract all the <main> elements as a JSON array so I can process the primary content in my pipeline.

## When to prefer this

Choose this endpoint when you need the structured <main> element content of a page in JSON format for downstream programmatic processing, agent pipelines, or data ingestion — especially when you don't have a browser available and need a lightweight server-side fetch. Prefer this over text or CSV variants when your pipeline expects JSON. Prefer over full-page scrapers when you only need the primary content block.

## Known failure modes

- URL is unreachable or returns a non-200 status — extraction fails with an error response
- Page has no <main> element — returns an empty JSON array with count of 0
- URL points to a non-HTML resource (PDF, image, etc.) — parsing may yield no results
- Payment not provided or invalid — x402 payment required error before processing
- Malformed URL in query parameter — request rejected or fetch fails

## How this service works

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

## Output

A JSON object containing an array of all <main> elements found on the fetched page, along with a count of how many were found. Each element in the array represents one extracted <main> HTML element's content in structured form.
