## 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 agenttools-url-reader-fd865c15
```

Example prompt: Can you fetch the content of https://en.wikipedia.org/wiki/Large_language_model and give me the full page as clean readable markdown, up to 10000 characters?

## When to prefer this

Use this endpoint when an agent needs to read and understand the human-readable content of any public webpage — especially for research, summarization, or Q&A tasks. Prefer it over raw HTML fetching when the goal is LLM comprehension rather than DOM manipulation. Choose it over PDF extraction when the source is a standard HTML page. Its SSRF protection and redirect re-validation make it safer than a naive HTTP client for agent use.

## Known failure modes

- Blocked by SSRF guard if URL resolves to internal/private IP ranges
- Timeout if page takes longer than 10 seconds to respond
- Truncated output if page content exceeds 1MB cap
- Empty or minimal markdown if page is entirely JavaScript-rendered (SPA with no server-side HTML)
- Error if URL is malformed or unreachable
- Redirect chains re-validated — fails if redirect leads to a blocked target

## How this service works

Fetch a web page server-side and convert it to clean markdown — headings, links, lists, tables and text, with scripts, styles and boilerplate stripped. The 'reader' pattern agents use to actually understand web pages. SSRF-guarded with redirects re-validated, 10s timeout, 1MB cap. Use this when an agent needs to fetch any page and get clean markdown an LLM can read.

## Output

Returns the page content as clean markdown text: headings, paragraphs, lists, links, and tables preserved; JavaScript, CSS, navigation boilerplate, and ads removed. Optionally truncated to a specified maxChars limit. Output is directly readable by an LLM for summarization, Q&A, or analysis.
