# Supply Chain ZK Proof Simulator MCP

> Supply Chain ZK Proof Simulator MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.017095/call, status unknown (last checked 2026-10-12).

Simulates zero-knowledge proof verification for supply chain queries, returning a boolean prediction result.

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-simulator-mcp-6493918f -d '<json body>'
```

Example prompt: Can you simulate a zero-knowledge proof for this supply chain claim: 'Shipment batch #A291 originated from a certified organic farm' — just return whether it holds or not.

## When to prefer this

Choose this endpoint when you need a lightweight boolean verdict on a supply chain assertion using zero-knowledge proof simulation logic, particularly when proof-of-compliance or proof-of-origin must be asserted without exposing raw underlying data. It is appropriate for rapid ZK simulation checks at low per-call cost ($0.017 USDC) via gasless x402 payments on Base L2.

## Known failure modes

- Missing required 'query' field returns a 400 validation error
- Ambiguous or malformed query string may yield an unpredictable prediction
- Payment failure via x402 protocol results in 402 Payment Required before execution
- Service downtime on api.m2mcent.com returns 5xx errors
- Query too long or unsupported format may cause processing failure

## 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 'prediction' boolean field indicating whether the supplied supply chain query holds true under zero-knowledge proof simulation logic.
