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 kevaremesh-service-uptime-checker-b8ac061b -d '<json body>'
```

Example prompt: Can you check if https://api.myservice.com/health is currently reachable, and let me know the HTTP status and how long it took to respond? Use a 5 second timeout.

## When to prefer this

Use this endpoint when you need a lightweight, fast HTTP reachability check via HEAD request without downloading the full response body. Ideal for uptime verification, pre-flight checks before dependent API calls, or detecting redirects. Not suitable for checking page content or verifying response body integrity.

## Known failure modes

- Private or local network targets are blocked and will return an error
- Timeout if the target does not respond within the specified timeout_ms (max 8000ms)
- Invalid or malformed URL input returns a validation error
- DNS resolution failures for non-existent domains
- Target returns non-standard HTTP responses that cannot be parsed

## How this service works

Buyer-first MCP procurement gateway that discovers, compares and routes live x402 APIs without making the buyer choose a provider.

## Output

Returns a JSON object with reachability boolean, HTTP status code, latency in milliseconds, final URL after redirects, redirect count, content type, the HTTP method used (HEAD), and the timestamp of the check. Also includes product and service metadata.
