## 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 x402-web-probe-fetch-to-markdown-hub-europe-germany-3c296788
```

Example prompt: Fetch the page at https://example.com and give me its content as Markdown — I want to see the title, whether it returned a 200, and the full text.

## When to prefer this

Choose this endpoint when you need to fetch and read the textual content of a public webpage from a European network location, particularly when you want clean Markdown output suitable for downstream LLM processing. Ideal for checking page availability and content simultaneously without needing an API key or account. Prefer over generic scraping services when low-cost pay-per-call micropayments (x402/USDC) are acceptable and European geolocation matters for latency or content accuracy.

## Known failure modes

- Non-200 HTTP status returned if target site is down or returns an error
- Empty or minimal markdown if page is JavaScript-heavy and requires client-side rendering
- Truncation flag set to true if page content exceeds size limits
- Payment failure if USDC/Base transaction is rejected or insufficient
- Timeout if target URL is slow to respond from the German hub
- TLS errors if target site has invalid or expired certificates

## How this service works

Pay-per-call website uptime/latency/TLS checks and fetch-to-Markdown, measured from Hub Europe (Germany). USDC on Base via x402. No account or API key.

## Output

A JSON object containing the fetched page's URL, title (string), HTTP status code (integer), full page content converted to Markdown (string), and a boolean indicating whether the content was truncated. Measured from a European (Germany) vantage point.
