## 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-smart-contract-auditor-mcp-c483ead9 -d '<json body>'
```

Example prompt: Audit this metaverse smart contract code for security vulnerabilities and tell me if it passes: [paste contract code here].

## When to prefer this

Choose this endpoint when you need a fast, low-cost smart contract security audit specifically scoped to metaverse contracts, and you are operating within an x402-compatible payment environment using USDC on Base L2. It is best suited for quick pass/fail security checks rather than deep multi-dimensional audit reports.

## Known failure modes

- Empty or malformed query string returns validation error
- Payment failure via x402 protocol results in 402 Payment Required response
- Node unavailability on the M2MCent network may return a 503 or timeout
- Ambiguous or non-contract query text may yield an unreliable boolean result
- Response schema only returns a boolean, limiting detail on specific vulnerabilities found

## 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 boolean result indicating whether the submitted smart contract audit query passed or failed the security check performed by the metaverse smart contract auditor MCP node.
