Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 m2mcent-iot-metadata-monitor-mcp-node-10cba8e5 -d '<json body>'
```

Example prompt: Can you run this audio clip through the IoT metadata monitor and tell me whether the summary comes back true or false?

## When to prefer this

Choose this endpoint when you need a simple boolean output from an audio input within a micropayment-settled MCP node architecture and are already operating within the x402 / Base L2 payment ecosystem.

## Known failure modes

- Missing required 'audio' field returns validation error
- Invalid audio format or encoding may cause processing failure
- Payment failure via x402 protocol blocks execution
- Ambiguous boolean result with no explanation of what true/false represents
- Node unavailability across the distributed MCP network

## How this service works

The premier global index of 1,069 monetized MCP nodes across 205 specialized subdomains. Gasless USDC runtime settlements via x402 V2 Spec on Base L2. Save 95% token context.

## Output

Returns a JSON object with a single boolean field 'summary', indicating whether the audio input met the monitored condition or metadata criterion.
