## 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 argonautworks-public-web-page-reader-api-e7ab4fbd
```

Example prompt: Can you read the content of https://example.org/about and give me a clean, readable summary of what's on that page? Fetch up to 20000 characters.

## When to prefer this

Choose this endpoint when you need to retrieve the readable text content of a known public static web page and want it returned as clean, sanitized Markdown. It is ideal for reading articles, blog posts, documentation pages, or any public HTML page where JavaScript rendering is not required. Prefer this over generic scraping tools when robots.txt compliance and content sanitization are important. Do not use it for authenticated pages, paywalled content, JavaScript-heavy SPAs, or when you need to crawl multiple pages or follow links automatically.

## Known failure modes

- URL is behind authentication or a paywall — returns error or empty content since auth bypass is not supported
- JavaScript-rendered content is missing — SPA pages where content requires JS execution will return skeletal HTML only
- robots.txt disallows fetching — robots directive is honored and content may be withheld or flagged
- URL exceeds 2048 characters — rejected by schema validation
- max_chars below 1000 or above 50000 — rejected by schema validation
- Page returns non-200 HTTP status — may return error or empty markdown
- Network timeout or unreachable host — fetch fails with an error response
- Non-HTML content types (PDFs, binary files) may not convert cleanly to markdown

## How this service works

A bounded, robots-aware reader for public static web pages that returns sanitized Markdown. It never executes JavaScript or bypasses authentication/paywalls.

## Output

A JSON object containing the page's content as sanitized Markdown text, page title, meta description, detected language, canonical and final URLs, cache state (hit/miss), robots.txt compliance status, content type, fetch timestamp, source state (fresh/cached), truncation flag, and character counts for original and returned markdown. Also includes a limitations array reminding the agent that fetched content is untrusted.
