## 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 readable-url-to-clean-markdown-via-x402-7ac0f2f7
```

Example prompt: Can you fetch https://blog.cloudflare.com/introducing-workers-ai and convert it to clean markdown so I can feed it into my LLM pipeline?

## When to prefer this

Choose this endpoint when you need to feed web page content into an LLM pipeline and want boilerplate-free, well-structured Markdown rather than raw HTML. It is ideal for single-page article extraction, documentation ingestion, and research pipelines where clean formatting (GFM tables, fenced code) matters. Prefer it over generic HTML scrapers when LLM readability and per-call micropayment billing (no subscription) are priorities.

## Known failure modes

- URL is unreachable or returns non-200 — likely returns an error object or empty content
- Payment not included or insufficient USDC — x402 payment required error
- Page is JavaScript-heavy SPA and content cannot be fully rendered — partial or empty markdown returned
- URL points to a binary file (PDF, image) rather than HTML — conversion may fail or return minimal output
- Rate limiting or timeout on the target URL — upstream fetch failure
