## 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-optimizer-mcp-node-67811131 -d '<json body>'
```

Example prompt: Run the M2MCent metaverse metadata optimizer node for hash '0xabc123def456' and tell me whether the result summary comes back true.

## When to prefer this

Choose this endpoint when you need to execute a specific M2MCent monetized MCP node identified by a hash and require a simple boolean summary result, especially when operating within the x402 gasless USDC payment protocol on Base L2.

## Known failure modes

- Missing or invalid 'hash' input returns a validation error
- Insufficient USDC balance for x402 payment causes payment failure
- Hash not found in the MCP node index returns an error or false summary
- Network congestion on Base L2 may cause settlement delays
- Malformed hash string may return an unexpected result or 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 a JSON object with a required 'summary' boolean field indicating whether the MCP node execution produced a positive result for the given hash input.
