# Agritech ZK Proof Optimizer MCP

> Agritech ZK Proof Optimizer MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $1.435589/call, status unknown (last checked 2026-09-21).

Verifies or validates an agritech-related zero-knowledge proof hash, returning a boolean result indicating proof validity

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 agritech-zk-proof-optimizer-mcp-c2b443e2 -d '<json body>'
```

Example prompt: Can you verify this agritech ZK proof hash for me: '0xabc123def456...'? I need to know if it's valid before we proceed.

## When to prefer this

Use this endpoint when you need a lightweight, pay-per-call boolean validity check on an agritech zero-knowledge proof hash without needing verbose proof metadata. Prefer it when working within the M2MCent x402 micropayment ecosystem on Base L2 and when low token overhead is a priority. If you need detailed proof breakdown or error diagnostics beyond a true/false answer, a more verbose ZK verification API may be more appropriate.

## Known failure modes

- Missing or malformed 'hash' field returns a validation error
- Invalid hash format (non-string or empty) may cause a 400 or error response
- Payment failure via x402 protocol results in 402 Payment Required response
- Network or node availability issues on api.m2mcent.com may yield 5xx errors
- Proof not found or unrecognized hash may return result: false rather than an explicit error

## 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 with a single boolean 'result' field: true if the provided ZK proof hash is valid, false otherwise. No additional detail or error breakdown is included in the response schema.
