# M2MCent Logistics ZK Proof Validator MCP

> M2MCent Logistics ZK Proof Validator MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.121051/call, status unknown (last checked 2026-10-11).

Validates zero-knowledge proofs for logistics use cases via a monetized MCP node endpoint using the x402 payment protocol

## Facts

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-validator-mcp-9f8d3d48 -d '<json body>'
```

Example prompt: Can you validate this zero-knowledge proof for my logistics shipment record and tell me if it checks out?

## When to prefer this

Choose this endpoint when you need to validate a zero-knowledge proof specifically in a logistics or supply chain context and are operating within the x402 micropayment ecosystem on Base L2. Prefer this over generic ZK validators if you need a pay-per-use, gasless USDC settlement model without maintaining your own validator infrastructure.

## Known failure modes

- Missing or empty 'prompt' field returns a validation error
- Malformed or non-ZK-proof input may return false or an error response
- Payment failure via x402 protocol results in a 402 HTTP response blocking execution
- Network or node unavailability may result in a timeout or 5xx error
- Invalid proof format may cause silent false negatives

## 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 'hash' field with a boolean value indicating whether the submitted ZK proof is valid (true) or invalid (false).
