# M2MCent Zero-Knowledge Model Execution Proof MCP

> M2MCent Zero-Knowledge Model Execution Proof MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.5/call, status unknown (last checked 2026-10-12).

Processes arbitrary data through a monetized remote MCP node with zero-knowledge model execution proof, settling payments gaslessly via x402 V2 on Base L2.

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-zero-knowledge-model-execution-proof-mcp-9269c2b2 -d '<json body>'
```

Example prompt: Process this data through the M2MCent zero-knowledge model execution proof node and give me back the transaction hash confirming the computation settled on Base L2.

## When to prefer this

Choose this endpoint when you need to execute a computation or model task through a monetized remote MCP node with cryptographic proof of execution, especially when gasless USDC micropayment settlement on Base L2 is required and you want to avoid consuming local token context.

## Known failure modes

- Insufficient USDC balance for $0.50 per-call fee — payment rejected
- Invalid or missing data field in request body — returns 400 error
- MCP node unavailable or overloaded — returns 503 or timeout
- x402 payment protocol negotiation failure — settlement not completed
- Malformed data string causing execution error on the remote node

## 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 transaction hash (txHash) confirming the gasless USDC settlement on Base L2, and a boolean success field indicating whether the computation completed successfully.
