## 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 tempo-halowerk-com-dns-resolution-time-check-for-redirects-6b0c7271 -d '<json body>'
```

Example prompt: Can you check the DNS resolution time for the redirect at https://example.com/redirect and tell me how long the DNS lookup is taking?

## When to prefer this

Use this endpoint when you specifically need to isolate and measure DNS resolution time within a redirect flow, as opposed to overall page load time or connection time. Prefer this when debugging slow redirects where DNS is suspected as the cause, or when benchmarking redirect DNS performance for monitoring purposes.

## Known failure modes

- Invalid or unreachable URL returns error
- Non-public or internal IP address rejected
- Malformed input schema returns validation error
- DNS timeout if domain is unreachable
- CSS selector matches no element if provided
- Rate limiting or payment failure returns 402
