## 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-logistics-smart-contract-validator-mcp-e42ef542 -d '<json body>'
```

Example prompt: Can you validate this logistics smart contract for me — query: 'shipment from Shanghai to LA, 30 days, FOB terms, auto-release on delivery confirmation'?

## When to prefer this

Choose this endpoint when you need to programmatically validate logistics smart contract terms via a monetized MCP node with gasless USDC micropayment settlement on Base L2. Prefer it over generic contract validators when working within a blockchain-native logistics workflow that requires x402 protocol payment rails.

## Known failure modes

- Missing required 'query' field returns a 400-level error
- Payment not processed via x402 protocol results in 402 Payment Required
- Malformed or ambiguous contract query may return an empty or null URL result
- Endpoint downtime or MCP node unavailability causes 5xx errors
- Insufficient USDC balance for the $0.406682 per-call fee blocks execution

## 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 'url' boolean field indicating whether the validation result links to a URL (though the schema notes the url field is typed as boolean, suggesting a pass/fail or reference indicator for the validated contract).
