## 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-metaverse-metadata-auditor-mcp-node-5fb787c2 -d '<json body>'
```

Example prompt: Can you run a metaverse metadata audit on this asset payload and tell me whether it passed validation?

## When to prefer this

Choose this endpoint when you need to audit or validate metaverse metadata through the M2MCent monetized MCP node network and are already set up for gasless USDC micropayments via the x402 protocol on Base L2. Best suited for automated pipelines that need a quick pass/fail metadata integrity check without rich error diagnostics.

## Known failure modes

- Malformed payload string returns an error or false status
- Payment failure via x402 protocol prevents execution
- Node unavailability on the M2MCent network causes timeout
- Insufficient USDC balance halts settlement and blocks the call
- Opaque false status with no error details makes debugging difficult

## 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 a JSON object with a boolean 'status' field indicating whether the metadata audit passed (true) or failed (false).
