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 hrtf-binaural-renderer-mcp-af863959 -d '<json body>'
```

Example prompt: Take this audio data and render it as a binaural 3D spatial audio output using HRTF processing so it sounds like it's coming from all around me when I listen through headphones.

## When to prefer this

Choose this endpoint when you need to apply HRTF-based binaural spatialization to audio data programmatically, especially in agentic pipelines for VR, gaming, immersive media, or headphone-optimized audio production where real-time or near-real-time rendering is needed.

## Known failure modes

- Invalid or malformed audio data in the 'data' field returns a 400 error
- Unsupported audio format may cause processing failure
- Overly large audio payload may time out or be rejected
- Missing 'data' field results in validation error
- Payment failure via x402 protocol prevents processing

## 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 processed binaural audio data that has been spatialized using HRTF (Head-Related Transfer Function) algorithms, suitable for playback through headphones to create a convincing 3D spatial audio experience.
