## 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 agent-json-reliability-web-markdown-endpoint-19ea8688 -d '<json body>'
```

Example prompt: Can you fetch the page at https://example.com/article and give me the content as clean Markdown so I can process it further?

## When to prefer this

Choose this endpoint when you need to fetch a public web page and receive its content as clean Markdown within a pipeline that already uses the Agent JSON Reliability service for JSON repair/validation. It's a convenient companion tool for agents that need readable web content without setting up a separate scraping service.

## Known failure modes

- URL is unreachable or returns a non-200 HTTP status — endpoint may return an error or empty result
- Page is JavaScript-rendered and content is not available in static HTML — Markdown output may be incomplete
- Malformed or missing URL input — likely returns a validation error
- Rate limiting or network timeout from the target URL — may result in partial or failed response
- Very large pages may time out or be truncated
