# PropTech ZK Proof Extractor MCP

> PropTech ZK Proof Extractor MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $1.299424/call, status unknown (last checked 2026-10-11).

Accepts a hash input and returns a boolean result, ostensibly performing a zero-knowledge proof extraction or verification in the PropTech domain.

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 proptech-zk-proof-extractor-mcp-d1418f1c -d '<json body>'
```

Example prompt: Can you verify this proptech ZK proof hash '0xabc123def456...' and tell me if it checks out as valid?

## When to prefer this

Use this endpoint when you need to validate or extract a boolean result from a zero-knowledge proof hash in a PropTech or real estate context, particularly when operating within an x402 micropayment environment on Base L2. Prefer this over generic hash-checking tools when the domain is specifically property technology or real estate attestations.

## Known failure modes

- Missing or malformed hash input returns a validation error
- Invalid hash format may return false rather than an error
- Payment failure via x402 protocol results in 402 response before execution
- Downstream ZK proof service unavailability causes timeout or 5xx error
- Empty string hash likely returns false or an error response

## 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

A JSON object containing a single boolean field indicating whether the provided hash passes the zero-knowledge proof validation (true = valid, false = invalid).
