## 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 prosody-pitch-analyzer-mcp-a64b41dd -d '<json body>'
```

Example prompt: Analyze the prosody and pitch of this speech sample for me — I want to know the intonation patterns, pitch range, and any notable stress or rhythm features in the audio data.

## When to prefer this

Choose this endpoint when you need automated, per-call prosody and pitch extraction from speech data without building a local speech analysis pipeline. Best for agents that need acoustic intonation features programmatically as part of a voice quality, emotion, or linguistics workflow.

## Known failure modes

- Invalid or malformed input data returns an error response
- Empty or missing data field causes processing failure
- Unsupported audio format or encoding may result in extraction errors
- Very short or silent audio clips may yield sparse or empty pitch metrics
- Network timeout for large audio payloads

## 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 structured prosody and pitch analysis including pitch contour, intonation metrics, rhythm features, stress patterns, and acoustic measurements extracted from the input speech data.
