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 iot-sentiment-simulator-mcp-52c80cf4 -d '<json body>'
```

Example prompt: Analyze the sentiment of this audio clip and tell me whether it's positive or negative — here's the audio data encoded as a string.

## When to prefer this

Use this endpoint when you need a fast, lightweight boolean sentiment classification for audio data within an IoT or MCP agent pipeline, especially when USDC micropayment settlement via x402 on Base L2 is acceptable and token-efficient processing is a priority.

## Known failure modes

- Missing 'audio' field returns validation error
- Malformed or non-audio string may return incorrect boolean
- Ambiguous audio data may yield unreliable sentiment classification
- Network or payment failure via x402 protocol may cause timeout
- Empty audio string may cause processing failure

## 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

A JSON object containing a single boolean 'result' field indicating whether the sentiment detected in the provided audio is positive (true) or negative (false).
