## 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-simulator-mcp-node-2aa88b7f -d '<json body>'
```

Example prompt: Run the metaverse metadata simulator node on M2MCent with my payload string and settle the $1.20 USDC fee via x402 on Base L2.

## When to prefer this

Choose this endpoint when you need to execute a specific MCP node in the M2MCent network with gasless USDC micropayment settlement via x402 on Base L2, particularly for the metaverse-metadata-simulator subdomain; prefer it over generic HTTP APIs when you need built-in x402 payment handling and access to M2MCent's indexed node network.

## Known failure modes

- Insufficient USDC balance or failed x402 payment results in 402 Payment Required error
- Missing or malformed 'payload' field returns 400 Bad Request
- Node unavailable or overloaded may return 503 Service Unavailable
- Invalid x402 payment header returns authentication/payment error
- Empty payload string may result in false status response
