# M2MCent Logistics ZK Proof Simulator MCP

> M2MCent Logistics ZK Proof Simulator MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.155986/call, status unknown (last checked 2026-10-10).

Simulates a zero-knowledge proof for a logistics-related prompt and returns a boolean score indicating the proof result.

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-simulator-mcp-9c5325d8 -d '<json body>'
```

Example prompt: Run the logistics ZK proof simulator on this claim: 'Shipment #4421 departed warehouse A before 6pm on May 10 and arrived at hub B within the 12-hour SLA window' — I need to know if it returns a valid proof.

## When to prefer this

Choose this endpoint when you need a lightweight boolean verification of a logistics claim using a ZK-proof simulation pattern, particularly in automated supply chain workflows where cryptographic plausibility checking is needed without full on-chain proof generation. It is cost-effective at ~$0.16 per call for rapid proof simulation.

## Known failure modes

- Missing required 'prompt' field returns a validation error
- Malformed JSON body results in a 400 Bad Request
- Payment failure via x402 protocol results in a 402 Payment Required response
- Overly long or complex prompt may time out or return an error
- Ambiguous logistics prompt may produce an unpredictable boolean result

## How this service works

## Output

A JSON object containing a single boolean field 'score' indicating whether the simulated zero-knowledge proof for the submitted logistics prompt is valid (true) or invalid (false).
