## 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 subagent-health-monitor-mcp-76e0c330 -d '<json body>'
```

Example prompt: Can you check the health status of my subagents and tell me which ones are currently running, degraded, or unresponsive?

## When to prefer this

Choose this endpoint when you need to programmatically check the health or operational status of subagents in a multi-agent system, especially within automated orchestration pipelines that require gate-checking agent availability before dispatching tasks. Prefer it over generic uptime monitors when dealing specifically with MCP-compatible subagents.

## Known failure modes

- Invalid or missing data payload returns a 400 error
- Subagent not found or unrecognized identifier returns empty or error response
- Payment not processed (x402 protocol) results in 402 response before health data is returned
- Upstream agent infrastructure unreachable causes timeout or 503 error
- Malformed JSON in input data field causes processing failure
