## 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 agentshelf-syntexa-ch-url-to-markdown-60120d4b -d '<json body>'
```

Example prompt: Can you fetch the main content of https://en.wikipedia.org/wiki/Large_language_model and give it to me as markdown text?

## When to prefer this

Choose this endpoint when you need to retrieve and read the primary textual content of a public web page in a clean, agent-friendly Markdown format. It is SSRF-safe, making it suitable for automated agent pipelines that must not access internal network resources. Prefer the free sandbox endpoint (/v1/sandbox/url-to-md) for testing or low-volume use; use this paid endpoint for production reliability.

## Known failure modes

- URL is unreachable or returns a non-200 status — fetch fails with an error
- URL targets a private/internal IP address — blocked by SSRF protection
- URL content is not parseable HTML (e.g. binary file) — may return empty or minimal markdown
- URL exceeds 2048 characters — rejected by input validation
- Page requires JavaScript rendering — static fetch may miss dynamically loaded content
- Payment of $0.005 USDC not included or fails — request rejected with 402

## How this service works

Call when an agent needs main content of a public http(s) URL as markdown plus title and final_url. SSRF-safe fetch. Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/url-to-md first.

## Output

Returns the main body content of the requested URL as a Markdown string, along with the page title and the final resolved URL (after any redirects). Content is cleaned of navigation, ads, and boilerplate to expose the primary readable content.
