# Supply Chain ZK Proof Optimizer MCP

> Supply Chain ZK Proof Optimizer MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.542245/call, status unknown (last checked 2026-10-10).

Accepts a hash string and returns a boolean result, purportedly for zero-knowledge proof optimization in supply chain contexts

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 supply-chain-zk-proof-optimizer-mcp-a70c0622 -d '<json body>'
```

Example prompt: Check whether this supply chain ZK proof hash is valid: 0xabc123def456...

## When to prefer this

Use this endpoint when you specifically need to validate a ZK proof hash in a supply chain context via a paid MCP node with x402 USDC micropayment settlement on Base L2.

## Known failure modes

- Missing required 'hash' field returns validation error
- Malformed or non-string hash value causes request rejection
- Payment failure via x402 protocol results in 402 response
- Service unavailability returns 5xx error
- Hash format mismatch may return false negatives

## 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 passed the zero-knowledge proof validation check.
