## 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-healthcare-metadata-indexer-mcp-1231c7d0 -d '<json body>'
```

Example prompt: Can you run this healthcare audio through the metadata indexer and tell me if it passes — the audio is encoded as a base64 string: [audio_base64_string]?

## When to prefer this

Use this endpoint when you need a simple pass/fail boolean evaluation of healthcare audio metadata, particularly in automated pipelines where a lightweight true/false signal is sufficient without needing detailed analysis output.

## Known failure modes

- Missing or malformed 'audio' field returns a validation error
- Non-base64 or unsupported audio format may result in processing failure
- Payment failure via x402 protocol prevents execution
- Network timeout on large audio payloads
- False negatives if audio encoding is corrupted
