Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 winwinhost-qa-watchdog-88350d42 -d '<json body>'
```

Example prompt: Can you run an external QA probe on example.com and check that /, /robots.txt, /sitemap.xml, and /llms.txt are all reachable and responding correctly, and also verify the page assets are loading?

## When to prefer this

Use this endpoint when you need an independent, third-party perspective on whether a domain and its key paths are publicly reachable — especially useful when local network conditions might be masking an outage, or when you need to verify SEO-critical files like robots.txt and sitemap.xml are accessible from outside your infrastructure.

## Known failure modes

- Invalid or unreachable domain returns error or failed probe status
- Domain DNS resolution failure reported in results
- Timeout if target domain is extremely slow to respond
- Invalid path formats may cause probe errors
- Payment failure (insufficient USDC balance) prevents call from completing
