## 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 web-production-8136ee-up-railway-app-e8e11ecd -d '<json body>'
```

Example prompt: Can you fetch https://en.wikipedia.org/wiki/Markdown and give me the page content as clean markdown — use the fresh tier so I get the latest version.

## When to prefer this

Choose this endpoint when you need to retrieve and process public web page content as clean Markdown for LLM ingestion, summarization, or analysis, especially when you want a paid-quality extraction with tier-based freshness control (cached through deep) rather than a free scraper that may return noisy HTML.

## Known failure modes

- Invalid or unreachable target_url returns an error
- Payment challenge not met results in 402 response
- Tier mismatch between query param and body causes payment amount conflict
- force_refresh requested on cached tier is not supported and may return an error
- Private or localhost URLs are rejected
- Rate limiting or payment failure aborts the request
