Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-zk-proof-monitor-mcp-7a15fba4 -d '<json body>'
```

Example prompt: Can you check whether the zero-knowledge proof for our latest shipment event is valid using the logistics ZK proof monitor?

## When to prefer this

Use this endpoint when you need a fast, pay-per-call boolean verification of logistics-related zero-knowledge proofs via a monetized MCP node on the M2MCent network, especially in automated agent pipelines where USDC micropayments via x402 are already supported.

## Known failure modes

- Malformed or missing prompt field returns a 400 error
- Payment not settled via x402 protocol results in 402 Payment Required
- Proof data not recognized or unparseable may return false without explanation
- Node unavailability or subdomain routing failure causes 5xx errors
- Ambiguous prompts may yield unreliable boolean outputs due to LLM interpretation

## 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 containing a single boolean field indicating whether the logistics ZK proof query passed validation (true) or failed (false).
