# NLP Smart Contract Optimizer MCP

> NLP Smart Contract Optimizer MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.661474/call, status unknown (last checked 2026-10-13).

Analyzes a text input and returns a boolean score indicating whether it passes smart contract optimization criteria

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 nlp-smart-contract-optimizer-mcp-a869244a -d '<json body>'
```

Example prompt: Can you run my smart contract description through the NLP smart contract optimizer and tell me if it passes the optimization check? Here's the text: 'This contract transfers ERC-20 tokens to a recipient upon meeting a threshold condition.'

## When to prefer this

Use this endpoint when you need a fast, binary pass/fail assessment of smart contract text for NLP optimization quality. Best suited for automated pipelines validating contract descriptions or code comments before deployment, where a simple boolean signal is sufficient and cost per call (~$0.66 USDC) is acceptable.

## Known failure modes

- Missing required 'text' field returns a validation error
- Empty string input may return false or an error
- Very long text inputs may be truncated or rejected
- Ambiguous or non-contract text may yield unreliable boolean scoring
- Payment failure via x402 protocol results in 402 status before processing

## 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 'score' boolean field — true if the input text passes smart contract optimization criteria, false if it does not. No additional explanation or metadata is returned.
