# M2MCent PropTech ZK Proof Auditor MCP

> M2MCent PropTech ZK Proof Auditor MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.454031/call, status unknown (last checked 2026-10-12).

Executes a ZK proof audit for property/real-estate data payloads and returns a boolean verification result via the x402 monetized MCP network.

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-proptech-zk-proof-auditor-mcp-122e3668 -d '<json body>'
```

Example prompt: Can you run a ZK proof audit on this property transaction payload and tell me if it passes verification?

## When to prefer this

Choose this endpoint when you need a lightweight cryptographic boolean verification of a proptech or real-estate-related payload using zero-knowledge proof methodology, especially within an x402 micropayment-enabled agentic workflow on Base L2. Prefer it when a simple pass/fail ZK audit result is sufficient and you want gasless USDC settlement.

## Known failure modes

- Invalid or malformed payload string returns an error or unexpected boolean false
- Payment failure via x402 protocol prevents execution
- Empty payload field causes a validation error
- Opaque boolean false with no explanation when proof is invalid — no error detail returned
- Network or node unavailability on the M2MCent subdomain

## 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 submitted proptech payload passed the ZK proof audit (true = valid, false = invalid).
