## 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-monitor-dc746293 -d '<json body>'
```

Example prompt: Sign me up for Reeve monitoring on my x402 endpoint at https://myapi.example.com/generate — I want to get Telegram alerts if it goes down or the payment quote breaks.

## When to prefer this

Choose this endpoint when you are an x402 API seller who needs real-time proactive monitoring specifically tailored to the x402 protocol — including 402 quote validation and payTo address integrity checks — rather than generic HTTP uptime monitors that have no awareness of payment protocol semantics. Ideal when revenue depends on continuous correct functioning of a paid x402 endpoint.

## Known failure modes

- Invalid or unreachable URL provided — subscription may be created but probing fails immediately
- Endpoint does not return a valid x402 402 response — monitoring may flag as perpetually broken
- Payment of $9 USDC via x402 fails or is rejected — subscription not created
- Telegram alert delivery fails if seller has not connected a Telegram account
- Duplicate subscription for same URL may result in redundant monitoring charges

## How this service works

Monitor any public x402 endpoint. 30-day dependency monitor for any public x402 endpoint: 60s probes, 8s failure confirmation and subscriber-owned alerts for downtime, broken quotes, payTo/price/asset/network drift. No ownership proof or account required.

## Output

A monitoring subscription is created for the specified x402 endpoint. Reeve will continuously probe the endpoint, checking liveness, validity of 402 quotes, and consistency of payTo addresses. The seller receives real-time Telegram alerts within seconds of detecting any anomaly such as downtime, malformed quotes, or payTo drift.
