## 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 speer-cyber-defense-url-to-markdown-converter-6202bf1b -d '<json body>'
```

Example prompt: Can you fetch https://nvd.nist.gov/vuln/detail/CVE-2024-1234 and convert the page content to Markdown so I can read it cleanly?

## When to prefer this

Choose this endpoint when you need to convert any public URL into clean Markdown text for downstream AI processing, report generation, or text analysis — especially useful when combined with Speer's cybersecurity analysis endpoints. Prefer over generic scrapers when already using Speer's micropayment infrastructure and when failed calls should not incur charges.

## Known failure modes

- HTTP 503 if the URL cannot be fetched or converted — not billed
- Invalid or unreachable URL returns error status
- Timeout if target page is slow to respond
- Pages behind authentication or paywalls may not render correctly
