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 spatial-audio-3d-synthesizer-mcp-76b07b8a -d '<json body>'
```

Example prompt: Can you spatialize this audio clip into a full 3D soundscape so it sounds like the source is moving around the listener in a 360-degree environment?

## When to prefer this

Choose this endpoint when you need to synthesize or render 3D spatial audio from existing audio data, particularly for VR, AR, gaming, or immersive media applications where positional sound is required.

## Known failure modes

- Invalid or malformed audio data input causing processing failure
- Unsupported audio format in the data field
- Empty or missing data field returns validation error
- Audio data too large or too long for single-call processing
- Corrupted base64 or encoded audio data

## 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 synthesized 3D spatial audio data — the input audio transformed with positional, environmental, and depth cues to create an immersive three-dimensional soundscape.
