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-metaverse-voice-synthesis-mcp-node-7a12d8c1 -d '<json body>'
```

Example prompt: Synthesize the phrase 'Welcome to the metaverse portal, traveler' into voice audio using the metaverse voice synthesizer MCP node.

## When to prefer this

Choose this endpoint when you need metaverse-specific voice synthesis executed through a monetized MCP node with gasless USDC micropayments via x402 on Base L2. Suitable for agents operating in metaverse or virtual world contexts that require per-call audio generation with low-overhead crypto payments.

## Known failure modes

- Payment failure: insufficient USDC balance or x402 transaction rejected
- Invalid query: empty or malformed query string returns error
- Node unavailability: the specific MCP subdomain node may be offline
- Status false: synthesis failed due to unsupported input or internal error
- Rate limiting: too many requests to the specific MCP node

## 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 boolean status field indicating whether the voice synthesis execution succeeded. Additional audio data or synthesis output may be included depending on the node implementation.
