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 ambisonics-b-format-encoder-mcp-81e0d280 -d '<json body>'
```

Example prompt: Can you encode this audio data into Ambisonics B-format so I can use it in my 360-degree VR video pipeline?

## When to prefer this

Choose this endpoint when you need to encode audio into the standard first-order Ambisonics B-format for use in VR, AR, 360 video, or binaural audio pipelines. Prefer it over generic audio conversion tools when the output specifically needs to be spatially represented with W/X/Y/Z ambisonics channels.

## Known failure modes

- Invalid or malformed audio data string returns an error
- Unsupported audio format may cause processing failure
- Empty data field causes rejection
- Non-audio data passed in the data field returns decoding error

## 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 B-format encoded ambisonics audio data (typically W, X, Y, Z channel representation) suitable for use in spatial audio decoders, VR engines, or binaural rendering pipelines.
