## 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 reeve-x402-endpoint-uptime-revenue-monitoring-annual-subscription-9d9ca38d -d '<json body>'
```

Example prompt: Sign me up for a year of Reeve monitoring on my x402 endpoint at https://api.myservice.com/premium-data — I want Telegram alerts if it goes down, breaks its 402 quote, or the payTo address drifts.

## When to prefer this

Choose this endpoint when you are an x402 API seller who wants automated, continuous monitoring of your endpoint's uptime, payment quote validity, and payTo address integrity over a full year. It is especially valuable if you depend on x402 revenue and need near-instant Telegram alerts rather than periodic manual checks. Prefer this over generic uptime monitors (e.g. UptimeRobot, Pingdom) because it understands x402-specific failure modes like broken 402 quotes and payTo drift — not just HTTP availability.

## Known failure modes

- Invalid or unreachable URL provided — endpoint cannot be registered if it does not respond
- Payment failure — USDC payment over x402 is required; insufficient balance or misconfigured wallet causes rejection
- Endpoint is not a valid x402 endpoint — returns error if the URL does not serve a proper 402 response
- Duplicate subscription — attempting to re-subscribe an already-monitored endpoint may return a conflict error
- Telegram alert channel not configured — monitoring may activate but alerts cannot be delivered without prior Telegram setup

## How this service works

Reeve probes every listed x402 endpoint, detects downtime, broken 402 quotes and payTo drift, and alerts sellers on Telegram in seconds. Pay in USDC over x402 itself.

## Output

A confirmed annual monitoring subscription for the specified x402 endpoint. Reeve will continuously probe the endpoint for HTTP availability, valid 402 payment quotes, and payTo address consistency, sending real-time Telegram alerts to the seller when any anomaly is detected. The response confirms enrollment in the monitoring service.
