## 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 yruz-uptime-checker-af8dd371 -d '<json body>'
```

Example prompt: Can you check if https://example.com is currently up and confirm that the word 'Welcome' appears somewhere on the page?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call uptime check for any URL or domain without setting up a full monitoring subscription. Particularly useful for one-off availability checks, pre-deployment verifications, or confirming content presence via keyword matching. Not ideal for continuous scheduled monitoring at high frequency, where a dedicated monitoring service would be more cost-effective.

## Known failure modes

- URL is malformed or missing — returns an error requiring a valid URL input
- Target domain is unreachable due to DNS failure — result reflects site is down
- Keyword not found in response body — result indicates keyword absence even if site is up
- Request timeout if target server is very slow — may be reported as down
- Invalid JSON input — API may reject the request

## Output

A JSON object with a 'tool' field set to 'uptime' and a 'result' object containing the availability status of the checked URL, indicating whether the site is reachable and optionally whether the specified keyword was found in the response body.
