## 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 agent-health-monitor-wallet-health-alert-subscription-30c5b556
```

Example prompt: Sign my wallet 0xd8da6bf26964af9d7eed9e03e53415d37aa96045 up for 30 days of automated health monitoring on Agent Health Monitor — I want webhook alerts whenever my health score, failure rate, or gas waste goes out of bounds.

## When to prefer this

Choose this endpoint when you need continuous, automated monitoring of a Base L2 agent wallet over a 30-day period with threshold-based webhook alerts. It is preferable over one-shot health checks when you want proactive notification rather than on-demand polling. Best suited for agent operators who want hands-off alerting without building their own monitoring infrastructure.

## Known failure modes

- Payment not received or insufficient USDC — subscription not created
- Invalid or malformed wallet address in path parameter — 400 error
- Duplicate subscription attempt for already-active address — may return conflict or idempotent response
- Webhook not yet configured — subscription is active but alerts cannot be delivered until POST /alerts/configure is called
- Service unavailability — 503 or timeout with no subscription created
