# M2MCent PropTech ZK Proof Validator MCP

> M2MCent PropTech ZK Proof Validator MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.01259/call, status unknown (last checked 2026-10-10).

Validates zero-knowledge proofs for property technology (PropTech) use cases via a monetized MCP node on the M2MCent 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-validator-mcp-33f8a767 -d '<json body>'
```

Example prompt: Can you validate this zero-knowledge proof string for our property ownership attestation: 'eyJwcm9vZiI6Ii4uLiIsInB1YmxpY0lucHV0cyI6W119'?

## When to prefer this

Choose this endpoint when you need to validate zero-knowledge proofs specifically in a PropTech or real estate context and require a lightweight, pay-per-call model via USDC micropayments. It is appropriate when you want privacy-preserving property data verification without running your own ZK validator infrastructure.

## Known failure modes

- Missing 'text' field in request body returns a validation error
- Malformed or non-ZK-proof text may return hash: false without descriptive error
- Payment failure via x402 protocol results in 402 response before execution
- Network or node unavailability on api.m2mcent.com subdomain may cause timeouts
- Empty string input may produce unpredictable boolean output

## 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 (boolean) indicating whether the submitted ZK proof text is valid. A true value indicates a successful validation; false indicates the proof failed verification.
