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 occlusion-audio-filter-mcp-13dffc9f -d '<json body>'
```

Example prompt: Can you apply an occlusion audio filter to this audio clip so it sounds like the sound source is behind a wall or barrier?

## When to prefer this

Choose this endpoint when you need to simulate acoustic occlusion effects on audio — particularly for game engines, spatial audio pipelines, or VR/AR environments where sound must realistically respond to physical barriers. Best suited for single audio clip processing where occlusion is the primary desired effect.

## Known failure modes

- Invalid or malformed audio data string returns an error
- Empty data field causes processing failure
- Unsupported audio encoding format may produce garbled output
- Oversized audio payload may be rejected or time out
- Missing required data field returns a 400-level 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 processed audio data with occlusion filtering applied, simulating the acoustic effect of sound being blocked or attenuated by physical obstacles, resulting in a muffled or dampened audio signal.
