## 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 vav-box-damper-mcp-cd53847b -d '<json body>'
```

Example prompt: Send a command to set the VAV box damper to 75% open position for zone 3 in the north wing HVAC system.

## When to prefer this

Choose this endpoint when you need to programmatically control or query VAV box damper positions in a building HVAC system, particularly in agentic building automation workflows that require pay-per-use M2M (machine-to-machine) control without a long-term subscription.

## Known failure modes

- Invalid or malformed data string returns error response
- VAV box identifier not found or unreachable
- Damper position value out of acceptable range
- Downstream HVAC controller timeout or unavailability
- Payment not processed — 402 response if USDC payment fails
