## 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 ciel-m2m-api-marketplace-uptime-monitor-fc38b421
```

Example prompt: Can you check the current uptime status of my service using the CIEL uptime monitor and tell me if it's available right now?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call uptime check without committing to a full monitoring SaaS subscription, especially in agentic workflows that need on-demand availability verification before proceeding. Prefer it over heavier infrastructure monitoring tools when you only need a single status lookup at $0.01 per call.

## Known failure modes

- Service not found or not configured for monitoring — returns empty or error result
- Payment failure via x402 — request blocked if USDC payment is not processed
- Network or host unreachable — sslip.io IP may be temporarily unavailable
- Invalid or missing input properties — may return generic error or empty result
- Upstream monitor data stale — result may reflect cached rather than real-time state
