## 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 horizonpulse-url-fetcher-clean-text-d3e64f31
```

Example prompt: Can you fetch the contents of https://example.com/blog/ai-trends and give me the clean readable text from that page?

## When to prefer this

Use this endpoint when you need to retrieve the readable text content from a public webpage in a clean, stripped format — ideal for summarization, information extraction, or reading web pages as plain text. Prefer this over the generic HTTP proxy sibling when you specifically want clean text/markdown output rather than raw HTML, headers, or JSON. SSRF safety makes it suitable for agent pipelines where user-supplied URLs are passed directly.

## Known failure modes

- Private or localhost URLs are blocked (SSRF protection)
- Response body exceeds ~200KB cap — content may be truncated
- Request times out after ~8 seconds for slow or unresponsive URLs
- Non-public or authentication-gated URLs return empty or error
- Non-HTML content types (PDFs, binaries) may not convert cleanly to text
- URL is malformed or missing — returns validation error

## How this service works

Fetch a public http(s) URL (?url=...) and return best-effort clean text/markdown; SSRF-safe with size/time caps

## Output

Returns best-effort clean text or markdown extracted from the fetched URL, stripped of HTML boilerplate, scripts, and styling. Includes the page's readable content with size capped at ~200KB and a time cap of ~8 seconds. Private/localhost URLs are blocked for SSRF safety.
